Embedding connects your content with the rest of the site: a note can end with a "Try yourself" problem, or show an app next to the theory it illustrates.

Note
A card with the summary of another note and a link to it.
Problem
A "Try yourself" card: readers solve it right there.
App
The app itself, ready to run.
Insert a problem
Search by title, tag or ID...
Addition of two vectors
Axially loaded steel bar

How to embed

  1. Place the cursor where the card should appear.
  2. Click Note, Problem or App in the toolbar.
  3. Search by title, tag or ID. Results appear while you type.
  4. Choose the item. The editor shows a preview card.

Changing or removing an embed

Double-click the card to choose a different item. Click it once and press Delete to remove it.

Only published items can be embedded, and a card disappears for readers if the embedded item is taken offline later.
