Structure Required Field Bulletin For Free

Fields marked with * are mandatory Using an asterisk (*) symbol content authors notify mandatory field. This is said to be one of the accessible modes of identifying a mandatory field, however this method also will be a problem with screen readers in certain times.

Providing Star (Asterisk) Symbol This is one of the most widely-adopted methods to notify the users that a form control is required. A star (asterisk) symbol is provided along with the label.

It depends on the context of the use. In HTML it will only work in a form that has input elements. The required attribute will flag when the field is empty.

On each form, mandatory fields must be clearly indicated: A distinctive sign (?*? symbol, ?mandatory? mention, etc.) ... If a symbol is used to declare mandatory fields, a statement placed at the beginning of the form must indicate that the symbol stands for a mandatory field.

The :required selector selects form elements which are required. Form elements with a required attribute are defined as required. Note: The :required selector only applies to the form elements: input, select and textarea. Tip: Use the :optional selector to select form elements which are optional.

Asterisk (*) next to a form control's label usually indicates it as "required". Oftentimes, this asterisk's purpose is then explained somewhere else on the page. Many users (especially screen reader users) may be confused with that, so be sure to make this information is easily accessible.

The "right" way to make a column mandatory is to set it to NOT NULL. If there are already nulls in the data then I would think those need to be set from a business standpoint (otherwise why is it mandatory?).

A distinctive sign (?*? symbol, ?mandatory? mention, etc.) must be provided in the label of each mandatory field. If a symbol is used to declare mandatory fields, a statement placed at the beginning of the form must indicate that the symbol stands for a mandatory field.
