##DESCRIPTION BN NG Search is an ANGULAR PIPE used to search recursively on a nested Array of objects dynamically.

##INSTALLATION

npm install bn-ng-search

##Import BnNgSearchModule

import { BnNgSearchModule } from 'bn-ng-search';
//......
//.....
 @NgModule({
 
  imports: [
    BrowserModule,
    BnNgSearchModule, //import the BnNgSearchModule in the NgModule
    FormsModule    
  ],
 
})
  //...

##Add the BN NG Search Pipe in the template

<input type="text" name="search" [(ngModel)]="key"/>
<bn-ng-tree [isSearch]="false" [items]="items | bnsearch: key: 'name': 'children'"></bn-ng-tree>

bnsearch is the pipe name, it accepts three parameters

1.key (string) = Search key (filter) which is a string used to search the array. 2.propertyName (string) = you can send the object's property name to be searched by the key. In the above example I used the property called 'name'. In your case, it may differ such as 'label','company' etc. based on your object 3.childrenPropertyName (string) = This is the name of the children property in the object. In the above example, the property name is 'children'. In your case it may differ such as 'child', 'branch' etc based on your object.

Note For showing a nested tree in angular, use the the following npm BN NG TREE
