+# ASP.NET Core MVC / Razor Pages: Auto-Complete Select
+A simple select component sometimes isn't useful with a huge amount of data. ABP Provides a select implementation that works with pagination and server-side search via using [Select2](https://select2.org/). It works with single or multiple choices well.
+
+A screenshot can be shown below.
+
+| Single | Multiple |
+| --- | --- |
+| ![autocomplete-select-example](../../images/abp-select2-single.png) |![autocomplete-select-example](../../images/abp-select2-multiple.png) |
+
+## Getting Started
+
+This is a core feature and it's used by the ABP Framework. There is no custom installation or additional packages required.
+
+## Usage
+
+A simple usage is presented below.
+
+```html
+<select asp-for="Book.AuthorId" 
+    class="auto-complete-select"
+    data-autocomplete-api-url="/api/app/author"
+    data-autocomplete-display-property="name"
+    data-autocomplete-value-property="id"
+    data-autocomplete-items-property="items"
+    data-autocomplete-filter-param-name="filter">
+
+    <!-- You can define selected option(s) here  -->
+    <option selected value="@SelectedAuthor.Id">@SelectedAuthor.Name</option>
+</select>
+```
+
+The select must have the `auto-complete-select` class and the following attributes:
+
+- `data-autocomplete-api-url`: * API Endpoint url to get select items. **GET** request will be sent to this url.
+- `data-autocomplete-display-property`: * Property name to display. _(For example: `name` or `title`. Property name of entity/dto.)_.
+- `data-autocomplete-value-property`: * Identifier property name. _(For example: `id`)_.
+- `data-autocomplete-items-property`: * Property name of collection in response object. _(For example: `items`)_
+- `data-autocomplete-filter-param-name`: * Filter text property name. _(For example: `filter`)_.
+- `data-autocomplete-selected-item-name`: Text to display as selected item.
+- `data-autocomplete-parent-selector`: jQuery selector expression for parent DOM. _(If it's in a modal, it's suggested to send the modal selector as this parameter)_.
+
+Also, selected value(s) should be defined with the `<option>` tags inside select, since pagination is applied and the selected options might haven't loaded yet.
+
+
+### Multiple Choices
+AutoComplete Select supports multiple choices. If the select tag has a `multiple` attribute, it'll allow to choose multiple options.
+
+```html
+<select asp-for="Book.TagIds" 
+    class="auto-complete-select"
+    multiple="multiple"
+    data-autocomplete-api-url="/api/app/tags"
+    data-autocomplete-display-property="name"
+    data-autocomplete-value-property="id"
+    data-autocomplete-items-property="items"
+    data-autocomplete-filter-param-name="filter">
+    @foreach(var tag in SelectedTags)
+    {
+        <option selected value="@tag.Id">@tag.Name</option>
+    }
+</select>
+```
+
+It'll be automatically bound to a collection of defined value type.
+```csharp
+    public List<Guid> TagIds { get; set; }
+```
+
+## Notices
+If the authenticated user doesn't have permission on the given URL, the user will get an authorization error. Be careful while designing this kind of UIs.
+You can create a specific, [unauthorized](../../Authorization.md) endpoint/method to get the list of items, so the page can retrieve lookup data of dependent entity without giving the entire read permission to users.
