Tag and Multi-tag

Coloured picklist Property kinds. Tag holds one option, Multi-tag holds several. Options can live on a single Collection, or come from one shared Global Tags pool you reuse everywhere.

A Tag is a coloured option you pick from a list — the same idea as a select in other tools. Multi-tag is the same, but you can pick several. They're perfect for things like mood, priority, project, or symptoms: a fixed-ish set of choices you want to filter and read at a glance.

There are four kinds, split on two simple questions.

One or many?

Tag — pick one option (Mood: happy).
Multi-tag — pick several (Symptoms: headache, tired).

You can convert between the two at any time from the property's ⋯ menu in the Collection builder — your existing entries come along. Switching a single Tag to Multi-tag keeps the chosen option; switching back keeps the first one.

Just this Collection, or shared everywhere?

This is the difference between a plain tag and a global tag.

Tag / Multi-tag (scoped) — the options live on this property, on this Collection. A Dish Collection's "Diet" tag has vegetarian / pescetarian / carnivore, and those options exist only there. Another Collection's tags are completely separate.
Global tag / Global multi-tag — the options come from your one shared pool, managed on the Global tags tab of Collections & Tags. Use these for labels you want to reuse across many different Collections — a #project or #area that means the same thing whether you're logging a workout, a note, or a meal.

Rule of thumb: if the options only make sense for one tracker, use Tag. If you'd retype the same labels on several trackers, use Global tag.

Using a tag

Wherever you log or edit an Entry — the entry page, a feed card, or the database table — a tag field shows your current pick as a coloured pill. Click it to open the picker:

Search the list, or just start typing.
Click an option to choose it (Multi-tag keeps the menu open so you can add more; Tag picks one and closes).
Create one — type a name that doesn't exist yet and hit Create. For a scoped tag the new option is added to this property; for a global tag it joins your shared pool.
Recolour, rename, or delete any option from the ⋯ menu next to it.

For Multi-tag, each chosen pill has an × to remove it.

Where options come from

You don't set options up in advance — you create them as you tag, right from the picker on an entry (just like Notion). Type a name that doesn't exist yet and hit Create: for a scoped Tag the option is added to that property; for a global Tag it joins your shared pool. Manage the shared pool any time on the Global tags tab.

The Global tags tab

Open Collections & Tags in the sidebar and pick the Global tags tab to manage your shared pool in one place — add new tags, recolour and rename them, drag to reorder, or delete. Every Global tag / Global multi-tag property across all your Collections picks from this same list, so a colour or rename here shows up everywhere at once.

Deleting an option

Deleting a tag option removes it from the picker. Entries that had it simply stop showing it — nothing else on the entry changes.
