# Ajax `Ajax` is a droplab plugin that allows for retrieving and rendering list data from a server. ## Usage Add the `Ajax` object to the plugins array of a `DropLab.prototype.init` or `DropLab.prototype.addHook` call. `Ajax` requires 2 config values, the `endpoint` and `method`. * `endpoint` should be a URL to the request endpoint. * `method` should be `setData` or `addData`. * `setData` completely replaces the dropdown with the response data. * `addData` appends the response data to the current dropdown list. ```html <a href="#" id="trigger" data-dropdown-trigger="#list">Toggle</a> <ul id="list" data-dropdown><!-- ... --><ul> ``` ```js const droplab = new DropLab(); const trigger = document.getElementById('trigger'); const list = document.getElementById('list'); droplab.addHook(trigger, list, [Ajax], { Ajax: { endpoint: '/some-endpoint', method: 'setData', }, }); ``` Optionally you can set `loadingTemplate` to a HTML string. This HTML string will replace the dropdown list whilst the request is pending. Additionally, you can set `onError` to a function to catch any XHR errors.
