The Multiple Selection component allows you to choose several options in a dropdown.
In this demo you have several examples of how to implement the various features.

This component uses the slim select library that can be found here https://github.com/brianvoe/slim-select. Currently using the version 1.27.0 

The component also has options that allow you to create various types of dropdowns with different functions.

This component will modify a given combo box, by prefixing a check box to allow multiple selection. This component has more features as well.

For example, you can define the maximum number of options that can be selected. This can be done by passing an integer value to a simple input variable.

Features List:

• Default: Allows you to select and unselect the options you want.
• Limit the number of options that can be selected: Allows you to select and unselect the options you want with a limit on the number of options that can be selected.
• Not closed on select: Allows you to select and unselect the options you want, keeping the ComboBox open until you click on another area.
• Preselect options: Allows you to preselect the options and then unselect and select again.
• Preselect and disable options: Allows you to preselect and deactivate the desired options, and you cannot select them again, but can still unselect them.
