FAQ (Frequently Asked Questions)

How do you make a quip collapsible section?

Can I expand or collapse all sections at once in my document? Yes. Click View on top of the toolbar and select Keep Outline Expanded. Alternately, click the floating menu to the right of the section and click Collapse/Expand.

What happens when a section is collapsed?

Collapsed sections don't print. So typically you'll want to expand all headings before you print a document. But you could, for example, use collapse and expand to selectively print only the sections you want.

How many external IDS can an object have?

You can designate up to 25 External ID fields per object. External ID fields must be Custom text, number or email fields.
