HI ​@Nataliya Sharova,

Thanks for reaching out. Could you confirm if you're using the Mind Map tool or connecting Diagramming Shapes in the board where the collapse feature isn’t working?

Here's a quick comparison (see screenshot): Mind Maps have branching connections and include the collapse/expand option, while Diagramming Shapes are connected with standard lines and do not have this feature.

If you’re using Mind Maps on both boards and still see a difference in functionality, please provide screenshots or a short video so we can better understand the issue and help troubleshoot!

Thank you for your quick reply! It appears that is accurate. On one board, I created a mind map, while on the other, I used a template from the list.

You’re welcome, ​@Nataliya Sharova! Glad to hear that cleared things up. If you need any further help with mind maps or anything else in Miro, feel free to ask.
