# Lookup tables

> Maintain the shared lists that power dropdowns across Advocora—tags, collections, gift designations and accounts, custom fields, and more.

**Lookup tables** are the shared lists that appear as dropdowns throughout Advocora. Keeping them tidy keeps everyone choosing from the same clean set of options.

## What you can manage

<CardGroup cols={2} />

<Note>
  **Event types** and **expense categories** appear only when the Events module is enabled.
</Note>

## Managing a list

Each table lets you add an entry, rename it, and (where allowed) remove it. Many show a **usage count** so you can see how widely an entry is used before changing it.

<Warning>
  If an entry is in use, Advocora may stop you from deleting it—or let you deactivate it instead—so existing records keep their meaning. Deactivating hides an option from new records without disturbing old ones.
</Warning>

<Tip>
  Agree on your designations and accounts as a team before you go live. Consistent lists here are what make your [reports](/reports/overview) clean later.
