AutoComplete is a functionality that let the user start typing characters and the autocomplete will try to give suggestions according to the characters entered. The collection can be a fxied JSON files (collection of strings or objects) or can also be an external remote resource to an external API. For a demo of what that could look like, take a look at the animated gif demo below.
If you want to pass the entire list to the AutoComplete (like a JSON file or a Web API call), you can do so using the collection or the collectionAsync (the latter will load it asynchronously). You can also see that the Editor and Filter have almost the exact same configuration (apart from the model that is obviously different).
export class GridBasicComponent {
columnDefinitions: Column[];
gridOptions: GridOption;
dataset: any[];
ngOnInit(): void {
// your columns definition
this.columnDefinitions = [
{
id: 'countryOfOrigin', name: 'Country of Origin', field: 'countryOfOrigin',
formatter: Formatters.complexObject,
dataKey: 'code', // our list of objects has the structure { code: 'CA', name: 'Canada' }, since we want to use the code`, we will set the dataKey to "code"
labelKey: 'name', // while the displayed value is "name"
type: FieldType.object,
sorter: Sorters.objectString, // since we have set dataKey to "code" our output type will be a string, and so we can use this objectString, this sorter always requires the dataKey
filterable: true,
sortable: true,
minWidth: 100,
editor: {
model: Editors.autocompleter,
customStructure: { label: 'name', value: 'code' },
collectionAsync: this.http.get('assets/data/countries.json'), // this demo will load the JSON file asynchronously
},
filter: {
model: Filters.autocompleter,
customStructure: { label: 'name', value: 'code' },
collectionAsync: this.http.get('assets/data/countries.json'),
}
}
];
this.gridOptions = {
// your grid options config
}
}
}By default HTML is not rendered and the label will simply show HTML as text. But in some cases you might want to render it, you can do so by enabling the enableRenderHtml flag.
NOTE: this is currently only used by the Editors that have a collection which are the MultipleSelect & SingleSelect Editors.
this.columnDefinitions = [
{
id: 'effort-driven', name: 'Effort Driven', field: 'effortDriven',
formatter: Formatters.checkmark,
type: FieldType.boolean,
editor: {
model: Filters.autocompleter,
placeholder: '🔍 search city',
type: FieldType.string,
// example with a fixed Collection (or collectionAsync)
filterOptions: {
showOnFocus: true, // display the list on focus of the autocomplete (without the need to type anything)
},
enableRenderHtml: true, // this flag only works with a fixed Collection
// collectionAsync: this.http.get(URL_COUNTRIES_COLLECTION),
collection: [
{ value: '', label: '' },
{ value: true, label: 'True', labelPrefix: `<i class="mdi mdi-plus"></i> ` },
{ value: false, label: 'False', labelPrefix: `<i class="mdi mdi-minus"></i> ` }
],
}
}
];All the available options that can be provided as editorOptions to your column definitions can be found under this AutocompleteOption interface you can also refer directly to Kraaden Autocomplete options.
editor: {
model: Filters.autocompleter,
editorOptions: {
minLength: 3,
} as AutocompleterOption
}You could also use external 3rd party Web API (can be JSONP query or regular JSON). This will make a much shorter result since it will only return a small subset of what will be displayed in the AutoComplete Editor or Filter. For example, we could use GeoBytes which provide a JSONP Query API for the cities of the world, you can imagine the entire list of cities would be way too big to download locally, so this is why we use such API.
The basic functionality will use built-in styling that is to display a label/value pair item result.
export class GridBasicComponent {
columnDefinitions: Column[];
gridOptions: GridOption;
dataset: any[];
initializeGrid() {
// your columns definition
this.columnDefinitions = [
{
id: 'product', name: 'Product', field: 'product',
filterable: true,
minWidth: 100,
editor: {
model: Editors.autocompleter,
alwaysSaveOnEnterKey: true,
editorOptions: {
showOnFocus: true,
minLength: 1,
fetch: (searchText, updateCallback) => {
// assuming your API call returns a label/value pair
yourAsyncApiCall(searchText) // typically you'll want to return no more than 10 results
.then(result => updateCallback((results.length > 0) ? results : [{ label: 'No match found.', value: '' }]); })
.catch(error => console.log('Error:', error);
},
} as AutocompleterOption,
},
}
];
this.gridOptions = {
// your grid options config
}
}
}This is the preferred way of dealing with the Autocomplete, the main reason is because the AutoComplete uses an <input/> and that means we can only keep 1 value and if we do then we lose the text label and so using an Object Result makes more sense. Note however that you'll need a bit more code that is because we'll use the FieldType.Object and so we need to provide a custom SortComparer and also a custom Formatters and for them to work we also need to provide a dataKey (the value) and a labelKey (text label) as shown below.
this.columnDefinitions = [
{
id: 'product', name: 'Product', field: 'product',
dataKey: 'id',
labelKey: 'name', // (id/name) pair to override default (value/label) pair
editor: {
model: Editors.autocompleter,
alwaysSaveOnEnterKey: true,
type: 'object',
sortComparer: SortComparers.objectString,
editorOptions: {
showOnFocus: true,
minLength: 1,
fetch: (searchText, updateCallback) => {
// assuming your API call returns a label/value pair
yourAsyncApiCall(searchText) // typically you'll want to return no more than 10 results
.then(result => updateCallback((results.length > 0) ? results : [{ label: 'No match found.', value: '' }]); })
.catch(error => console.log('Error:', error);
},
} as AutocompleterOption,
}

The previous example can also be written using the renderItem callback and adding classes, this is actually what Slickgrid-Universal does internally, you can do it yourself if you wish to have more control on the render callback result.
export class GridBasicComponent {
columnDefinitions: Column[];
gridOptions: GridOption;
dataset: any[];
initializeGrid() {
// your columns definition
this.columnDefinitions = [
{
id: 'product', name: 'Product', field: 'product',
filterable: true,
minWidth: 100,
editor: {
model: Editors.autocompleter,
alwaysSaveOnEnterKey: true,
customStructure: {
label: 'itemName',
value: 'id'
},
editorOptions: {
showOnFocus: true,
minLength: 1,
classes: {
// choose a custom style layout
// 'ui-autocomplete': 'autocomplete-custom-two-rows',
'ui-autocomplete': 'autocomplete-custom-four-corners',
},
fetch: (searchText, updateCallback) => {
yourAsyncApiCall(searchText) // typically you'll want to return no more than 10 results
.then(result => updateCallback((results.length > 0) ? results : [{ label: 'No match found.', value: '' }]); })
.catch(error => console.log('Error:', error);
},
renderItem: {
layout: 'twoRows',
templateCallback: (item: any) => `<div class="autocomplete-container-list">
<div class="autocomplete-left">
<span class="mdi ${item.icon} mdi-26px"></span>
</div>
<div>
<span class="autocomplete-top-left">
<span class="mdi ${item.itemTypeName === 'I' ? 'mdi-information-outline' : 'mdi-content-copy'} mdi-14px"></span>
${item.itemName}
</span>

</div>
<div>
<div class="autocomplete-bottom-left">${item.itemNameTranslated}</div>
</div>`,
},
} as AutocompleterOption,
callbacks: {
// callback on the AutoComplete on the instance
renderItem: {
templateCallback: (item: any) => {
return `<div class="autocomplete-container-list">
<div class="autocomplete-left">

<div>
<span class="autocomplete-top-left">

}If you want to add the autocomplete functionality but want the user to be able to input a new option, then follow the example below:
this.columnDefinitions = [{
id: 'area',
name: 'Area',
field: 'area',
type: FieldType.string,
filter: {
model: Filters.autocompleter,
filterOptions: {
minLength: 0,
forceUserInput: true,
fetch: (searchText, updateCallback) => {
updateCallback(this.areas); // add here the array
},
}
}
},
];You can also use the minLength to limit the autocomplete text to 0 characters or more, the default number is 3.
You might want to change the dimensions of the drop container, this 3rd party library has a customize method to deal with such a thing. Slickgrid-Universal itself is removing the width using this method, you can however override this method to change the drop container dimensions
this.columnDefinitions = [
{
id: 'product', name: 'Product', field: 'product', filterable: true,
editor: {
model: Editors.autocompleter,
alwaysSaveOnEnterKey: true,
// example with a Remote API call
editorOptions: {
minLength: 1,
fetch: (searchTerm, callback) => {
// ...
},
customize: (_input, _inputRect, container) => {
// change drop container dimensions
container.style.width = '250px';
container.style.height = '325px';
},
} as AutocompleterOption,
},
];
