how to filters tags except some

[vpl]

Hi,

I'm struggling with a filter expression and look for support ...

I want to propose in a drop down select, a list of existing tags except one

I have the following tags

 - APT

 - SP

 - Experiment

And I would like to display in my drop down, all the tags except the 'Experiment' one

I've tried multiples things but nothing works ...

<$select tiddler=<<currentTiddler>> field="projectId"
<$list filter='[tags[]]:and[!tags[Experiment]]'>
<option value=<<currentTiddler>>><$view field='title'/></option>
</$list>
</$select>

Any idea ;.....

Thanks a lot

Regards

Hi,

You should try: `[tags[]] -[[Experiment]]` (without the backticks) as the filter. See: https://tiddlywiki.com/#Filter%20Expression near the end of the tiddler.
