Control key settings for the block, including making values sensitive so they aren’t stored in our database and setting the block as required, making it mandatory for users to select an option before proceeding.

Set the block’s visibility to show only on mobile, desktop, or hide it completely. Additionally, you can select a background color for the block.

Control the block’s layout by adjusting its width (S, M, L, or maximum) and setting the block's padding from the top, bottom, left, and right.

System Labels define how your data is stored and organized, while Variables let you reference and display that data dynamically throughout your flow. You can set a label for the whole block and add a system answer to keep your data structured.

After clicking on a building block, you’ll find the Design section on the right. You can quickly apply a preset style tailored to that block type. Also, customize colors, fonts, and spacing to match your flow.

When you apply a design to one block type, it automatically updates all blocks of that type across your flow. This keeps your design consistent, clean, and easy to maintain without styling each block manually.
