method_block_theme_label_styles

apply_filters( 'method_block_theme_label_styles', mixed $styles )

Filters the label style options available in the Theme Button block.

Description

Registers named label style options that appear in a “Label Style” dropdown in the Theme Button block’s Inspector panel. Each style maps to a CSS class applied to the <span class="method-button-label"> element on the frontend.

When this filter returns false (the default), the label style selector is hidden entirely.

Parameters

$styles (array|false) :
An associative array where keys are CSS class names and values are display labels. Pass false to hide the control.

array(
    'label-uppercase'  => 'Uppercase',
    'label-small-caps' => 'Small Caps',
    'label-italic'     => 'Italic',
)

array(
    'label-uppercase'  => 'Uppercase',
    'label-small-caps' => 'Small Caps',
    'label-italic'     => 'Italic',
)

Usage

add_filter( 'method_block_theme_label_styles', 'mytheme_label_styles' );

function mytheme_label_styles( $styles ) {
    return array(
        ''                 => 'Default',
        'label-uppercase'  => 'Uppercase',
        'label-small-caps' => 'Small Caps',
    );
}

add_filter( 'method_block_theme_label_styles', 'mytheme_label_styles' );

function mytheme_label_styles( $styles ) {
    return array(
        ''                 => 'Default',
        'label-uppercase'  => 'Uppercase',
        'label-small-caps' => 'Small Caps',
    );
}

Notes

• The selected key is stored in the block’s labelStyle attribute and added directly as a CSS class on the label <span> element: <span class="method-button-label {labelStyle}">.
• Unlike method_block_theme_button_styles, the key is used as‑is as a class name — no prefix is added.
• You must define the corresponding CSS in your child theme’s stylesheet.
• The data is passed to the editor via themeButtonData.labelStyles.
