The Label block is used to associate descriptive text with a single form field, such as an input, textarea, or select element. It generates an accessible <label> element that links the label text to its corresponding form control, improving both usability and accessibility for all users.
To add a Label block, create a new form and open the Block Inserter tool. Use the search bar to find the Label block and click on its icon to insert it into the editor.
You can also choose the Label block from the “Block Inserter” (+) pop-up window when you click on the (+) sign.
