What is the Element Picker?

When you open the WP Interactions settings from the top toolbar and pick Element Interaction, you will need to select an Element Trigger from the dropdown list that follows.

The Element Picker consists of 4 Element Triggers:

1. Block
2. Block Name
3. CSS Class
4. CSS Selector

Picking Block or Block Name will allow you to create an interaction for a specific block only.

Picking CSS Class or CSS Selector will allow you to create an interaction for multiple elements in the page.
