The subject revolves around an Angular directive tailored for integrating Bootstrap dropdown functionality. This directive necessitates the utilization of AngularJS version 1.2.x alongside Bootstrap 3 to function correctly.
Versions and Features
Initially, version 0.1.0 of this directive was introduced, offering basic functionalities within the Bootstrap dropdown (bsDropdown). It includes the ability to set a default value using `ng-model` and to detect changes via `ng-change`. Progressing to version 0.1.1, the latest update at the time, an enhancement was made by incorporating a bootstrap divider into the bsDropdown.
Integration Guide
To incorporate the angular-bootstrap-dropdown directive into a project, one must first ensure the inclusion of the `bsDropdown.min.js` script, typically found within the distribution folder, into the HTML document of the project.
```html
<script src="bsDropdown.min.js"></script>
```Following this, the directive can be integrated into an Angular module by adding `ng.bs.dropdown` to the list of module dependencies.
```javascript
angular.module("demoApp", ['ng.bs.dropdown'])
```This setup paves the way for utilizing the angular-bootstrap-dropdown features within an application.
Usage Instructions
The directive offers a suite of attributes to customize the dropdown’s behavior and appearance:
- `bs-dropdown-display`: Utilize this attribute to set a default display text for the dropdown when no value is pre-selected;
- `bs-dropdown-items`: This attribute specifies the options available within the dropdown menu;
- `ng-model`: Essential for setting the default selected value within the dropdown;
- `ng-change`: A handy attribute to capture and respond to changes in the dropdown’s selection;
- `bs-dropdown-divider`: Employ this to define dividers within the dropdown, aiding in the organization of options. For instance, `bs-dropdown-divider=”{{[2,5]}}”` delineates dividers after the second and fifth options;
- `bs-dropdown-multi`: Activates the multi-select feature of the dropdown, allowing for the selection of multiple options simultaneously.
Through careful adherence to these guidelines, developers can effortlessly integrate and leverage the angular-bootstrap-dropdown directive in their web projects, enhancing the user experience with dynamic and responsive dropdown menus.
