When you are working in the container topic you can add new content above an embedded topic using the following methods.

Embedded topic has non-embedded content above it

Make your adjustments to the non-embedded content in the container topic as normal.

Embedded topic has another embedded topic above it

When there are two embedded topics, one directly following the other, remove the second embedded topic, make your adjustments, then re-embed the topic you removed.

Embedded topic is the first content in the container topic

• When the first content in the container topic is an embedded table, put the cursor at the start of the first cell and press ENTER. For more information see Adding Content Above an Embedded Table.
• For all other embedded content, remove the embedded topic, modify the container content, then re-embed the topic you removed.
