Click the “+” icon in the left navigation panel, just above the Welcome Block, to start adding questions.

Once a block is added, you can:

• Click directly on any block to edit it
• Rearrange or duplicate blocks as needed ( Note: If logic has been configured in a study, you will not be able to rearrange it ).
• Use the " Add block " buttons above or below an existing block to quickly add a new one in the desired position.

Step 7: Media Blocks

You’ll see different types of blocks grouped into three sections:

• Basic
• Advanced
• Media

In Media section, You’ll find two block types:

• Local File: Upload media (images/videos) from your computer. Supported formats include MP4, MOV, JPG, PNG (Max 200 MB; one file per block).
• YouTube/Vimeo: Embed public video links by pasting the URL. 

Click on any block to add it to your study. 

Step 8: Customize Each Media Block

Once added, use the configuration panel to:

• Upload or paste your media link
• Add a title
• Configure block settings using the right-hand Properties panel - you can add categories and enable technologies based on your study’s requirements.
• Combine with a follow-up question (e.g., thumbs up/down, text feedback) if desired

If you’re using Media Blocks along with follow-up questions (e.g., thumbs up/down, open text, etc), you can guide the flow using the Logic tab in the top navigation.
