What validations are possible?

Short and long text fields:

A minimum and a maximum number of characters.

Email fields:

Allow or block emails from a certain domain (for example, don’t allow gmail.com or yahoo.com).

Number fields:

Number fields support several validation options:

• Min value and Max value — restrict the accepted range of numbers.

• Decimal places — set how many decimal places are allowed.
• Allow negative numbers — choose whether negative values are accepted.
• Unit — display a unit label alongside the field (for example, kg, USD, or %).
