@Arvind To achieve this, you can configure the "OnChange" event on the Multiselect control and call a Data Transform to set the properties based on the selected options. Instead of refreshing the entire section, you can use visibility conditions on the sections you want to display.

These conditions should be based on the properties set in the Data Transform.

This way, the Multiselect control will not clear the dropdown after each selection, and the appropriate sections will be displayed based on the selected options.

Hi @Arvind, is your multi-select and the "to-be-displayed-section" all in one section? 

Can we try creating one wrapper section first where we can have the multiselect control and an embedded section (say A) inside it, which is the conditional section. Now, when you select values from the multiselect you can use "refresh other section" and refresh A. This way the refresh dependency of A will be isolated from the main section.
