I have a grouped select2 list that uses pagination to load 30 list items at a time. Each <optgroup> contains one or more <option> list items.
Feature request: an option group can cross the boundary of 30 items. When this happens, groups with the same labels at the page boundaries should be merged.
Example
optgroup group 1 contains 31 options, AJAX page size is 30.
AJAX Page 1
{
"results" : [
{
"text" : "group 1"
"children" : [
{
"id" : "item1"
"text" : "first item"
},
{
"id" : "item2"
"text" : "second item"
},
// items 3 to 29 omitted for brevity
{
"id" : "item30"
"text" : "thirtied item"
}
]
}
]
"pagination" : {
"more" : true
}
}AJAX Page 2
{
"results" : [
{
"text" : "group 1"
"children" : [
{
"id" : "item31"
"text" : "thirty-first item"
}
]
}
]
"pagination" : {
"more" : false
}
}Expected result
The code should recognize that page 2 should be merged with page 1 instead of appended, because the group header is the same.
<optgroup label="group 1">
<option value="item1">first item</option>
<option value="item2">second item</option>
<!-- items 3 to 29 omitted for brevity -->
<option value="item30">thirtied item</option>
<option value="item31">thirty-first item</option>
</optgroup>Actual result
<optgroup label="group 1">
<option value="item1">first item</option>
<option value="item2">second item</option>

<option value="item30">thirtied item</option>
