Customize the dropdown with your own style, and use the controller to programmatically control the dropdown. 11 | 12 | ## Breaking Changes in v3.0.0 13 | 14 | - The `MultiSelectDropDown` widget has been renamed to `MultiDropdown`, which now supports `FormValidation`. 15 | - The `MultiSelectController` methods have been updated/renamed. 16 | - The `ValueItem` class has replaced the `DropdownItem` class. 17 | - The `.network` constructor has been removed and has been replaced with the `future` constructor, which accepts a future callback to fetch the data from the server. Use it to handle future your own way. 18 | - `onOptionsSelected` has been replaced with `onSelectionChange`. The `onSelectionChange` callback is called whenever the selection changes in the dropdown, whether it is selected or deselected. 19 | - A lot of parameters have been renamed and updated. Please check the documentation for the updated parameters. 20 | 21 | ## Links 22 | 23 | [Preview](#preview) | [Controller](#controller) | [Parameters](#parameters) 24 | 25 | ## Preview 26 | 27 | [](screenshot_1.png) 28 | [](screenshot_2.png) 29 | [](screenshot_3.png) 30 | [](screenshot_4.png) 31 | 32 | ## Controller 33 | 34 | You can use the controller to programmatically select/unselect items, clear the selection, and get the selected items, set disabled items, show/hide the dropdown.
