[Categorizations](https://success.join.build/en/knowledge/project-settings?hsLang=en#categorizations) # Disabling Built-in Categorizations (Legacy) ## Learn how to disable Join's built-in MasterFormat and UniFormat categorizations on legacy projects and use custom categories instead. ***Caution**: This is only applicable to projects created before 06/16/2023* Join provides two built-in categorizations for specific versions of [MasterFormat and UniFormat](https://success.join.build/en/knowledge/using-masterformat-and-uniformat-in-join?hsLang=en). If your project uses a different version of either of these work breakdown structures or does not use them, you can disable them. ***Best Practice:** Unless your MasterFormat and UniFormat codes align with the built-in versions, we recommend disabling them and using [custom categories](https://success.join.build/en/knowledge/getting-started-with-custom-categories?hsLang=en).* Once disabled, the option to group and filter by the disabled categorization(s) is hidden on Items, Milestone Estimates and Budgets, Dashboards, Reports, and limiting access to Collaborators by Category. Doing so will help eliminate confusion when using similar category names for your project's version of UniFormat and MasterFormat. #### Disabling Built-in Categorizations 1. Click **Settings** in the [navigation panel](https://success.join.build/en/knowledge/how-to-navigate-in-a-project?hsLang=en#navigation_bar) 2. Scroll down to the **Categorizations**section 3. Click the toggle next to the Built-in Categorization(s) you want to disable 4. Click the **Ok** button to confirm ![](https://success.join.build/hubfs/image-png-Mar-25-2022-03-38-39-98-PM.png) ***Note:*** *Built-in Categorizations can be re-enabled anytime, and any previous Category information will remain intact.*   -
