Select (Bootstrap)
Description
Provides a popdown list of items which can be selected. Multiple selections are allowed.
Compared the Dropdown control, it acts more like other Input controls, with a header and a footer. Dropdown acts more like a button and does not allow multiple selections.
Popovers and Tooltips are supported.
Note: Changes were made to the Bootstrap 4 version of this control, starting with AppStudio 7.2.
- .addItem changed from(item, type) to (text, value, selected, disabled)
- .value renamed to .item
- .value now saves the internal value for the item.
