Details

This update function works similarly to update_select_input, but is specifically designed for toolbar_input_select. It allows you to update the select’s label, icon, choices, selected value(s), and label visibility from the server.

Note that you cannot enable or disable the tooltip parameter after the select has been created, as this affects the select’s structure and ARIA attributes. Please use update_tooltip to update tooltip text.

When a tooltip is created for the select input, it will have an ID of "{id}_tooltip" which can be used to update the tooltip text dynamically via update_tooltip.

Examples

#| standalone: true
#| components: [editor, viewer]
#| layout: vertical
