Can not find addon "Bootstrap4 - Dropdown Addon" after installing

Hello all,
Has anyone used addon “Bootstrap4 - Dropdown Addon”?
I installed this addon, then execute recording but I can not find this addon in Action.
If anyone used this addon, please show me how to use it.
Thank you

Hi @hoaithu2712, and welcome to our community.
‘Bootstrap4 - Dropdown’ is the name of the addon.
In this addon, you have the ‘Select item’ action.
Search for the ‘Select item’ action to use.

I tried to search “Select item” in Action after installed Bootstrap4 - Dropdown addon but i still can not find that action. It happends similarly with Bootstrap4 - Button Group.
Could you try to install these addons and get me know? :frowning:
