Choice fields
Let editors pick from a set of options you define. All are free. Each option is a value : Label pair — you read the value in code and show the Label to editors.
Select Free
A dropdown of choices.
Configure
Your list of choices (one value : Label per line), a default, Allow null (an empty option), and Allow multiple (a multi-select).
Stores
The chosen value as a string — or an array of strings when Allow multiple is on.
Display
<?php echo esc_html( fstn_get_field( 'status' ) ); ?>
<?php // multiple: ?>
<?php foreach ( (array) fstn_get_field( 'tags' ) as $tag ) : ?>
<li><?php echo esc_html( $tag ); ?></li>
<?php endforeach; ?>Checkbox Free
A list of options where several can be ticked.
Configure
Choices, defaults (one or more), and layout.
Stores
An array of the checked values (empty array when none).
Display
<ul>
<?php foreach ( fstn_get_field( 'features' ) as $feature ) : ?>
<li><?php echo esc_html( $feature ); ?></li>
<?php endforeach; ?>
</ul>Radio Free
A list of options where exactly one is selected.
Configure
Choices, a default, and layout (vertical or horizontal).
Stores
The chosen value as a string.
Display
<span class="size size--<?php echo esc_attr( fstn_get_field( 'size' ) ); ?>">
<?php echo esc_html( fstn_get_field( 'size' ) ); ?>
</span>Button Group Free
Like Radio, but shown as a row of buttons — good for a small, always-visible set of options.
Configure
Choices, a default.
Stores
The chosen value as a string.
Display
<?php echo esc_html( fstn_get_field( 'alignment' ) ); ?>True / False Free
A single on/off toggle.
Configure
A message shown beside the toggle, and the default state.
Stores
A bool.
Display
<?php if ( fstn_get_field( 'is_featured' ) ) : ?>
<span class="badge">Featured</span>
<?php endif; ?>in_stock) and friendly labels (In stock). You can then use the value directly in a CSS class or a query.
