Display the header only if there are notes with some tag (dataviewjs)

[m.prokhorov]

Things I have tried

Please help me with plugin dataviewJS.

There are notes with a tag = #tag.

I can use this inline code:

Number of notes with tag: $= dv.pages("#tag").length

I need to display the header only if there are notes with this tag.

Something like this:

IF

$= dv.pages("#tag").length > 0

Then

dv.header(6, ‘tag’);

I don’t get exactly what you want to achieve - which header do (or don’t) you want to display where?

This header in code dataviewjs will always be displayed:

dv.header(6, 'tag');

I need add some code to hide header if there are NO notes with this tag.
