In the "Administration" menu, you will find the "Lot" tab.

When your account is created, a tree structure is suggested to you.

If you wish to modify it, this is where everything happens.

The category section groups the different trades. You have the ability to edit, delete or add categories.

On each row, you have the ability to edit the elements using the "pencil" icon:

You can edit the name, change the category, add a description and change the color.

Using the "trash" button, you can also delete a row.

Using the "+" button at the top right, you can add as many rows as you wish.

Lots are used in the site section and are suggested to you with each new creation.
