Hi @Sam.sayer!
Thank you so much for the screenshot! That visual is super helpful and perfectly explains what you are trying to achieve.
Yes, this is absolutely possible! It looks like our Collapse and Expand feature is what you need. It allows you to build a detailed sub-process and then shrink it down to save space on your main flowchart.
Since you want to keep your main flow using standard process boxes, here is a great way to set this up so it perfectly matches your mockup:
-
Leave your "Ask who wants tea" --> "Make Tea" --> "Give Tea" standard process boxes exactly as they are.
-
Drag a Container shape (like a Rectangle Container) onto your canvas, placing it below the "Make Tea" step.
-
Build your detailed "Start to End" sub-process directly inside that container.
-
Draw a line connecting your standard "Make Tea" shape down to the Container (just like the downward arrow in your screenshot!).
-
Select the border of the container. Open the Contextual Panel on the right side of the canvas, and under "Shape Options", click the Collapse icon.
The container will shrink down into a compact shape at the end of your arrow! The main view stays uncluttered to show the high-level flow, and whenever someone needs the operational detail, they can simply select that collapsed shape and click the Expand icon.
For a visual walkthrough of this feature, check out our Help Center article here: How do I collapse and expand content in Lucid?
Let me know if you give this a try and have any questions!
Best,
Justin J.
