- Add a new field
Go to the Time Slot Pro > Settings > Booking Form page in your WordPress dashboard. To create a new custom field, click the +Add Field button at the bottom left of the Custom Form Fields section, or start by editing the first empty field already shown.
Next, choose the type of field you want to add, checkbox, file upload, number, radio buttons, dropdown select, text, or textarea. Choose whether to require the field (Yes) or make it optional (No). Then add a clear label so users know exactly what information to enter.
- Add placeholders
For text, number, select, and textarea fields, enter some text that gives users a quick hint about what to type. The placeholders will appear as faint text inside the form field will disappear once your user starts entering information.

- Add options
For select dropdown and radio button fields, add choices for your users to pick from. Click the plus (+) button to add more options, and the remove (X) button to delete an option.

- Rearrange fields
To change the order of your fields, click and hold the six dots on the left side of a field. Then drag it up or down to where you want it. The fields on your booking form will automatically update to match this new order.

- Save your fields
Click the Save Changes button at the bottom of the page. The booking form will show your new field right away. When a customer completes the form, you can review their information on the Customers page in the Time Slot Pro settings anytime.
