test.php

<?php

function custom_slider_steps( $output, $params ) {
    $output['settings']['YOUR_SLIDER_FACET_NAME']['range'] = array(
        'min' => array( 0.001 ),
        '25%' => array( 0.01, 0.01 ),
        '50%' => array( 1, 1 ),
        '75%' => array( 100, 100 ),
        'max' => array( 250000 )
    );
    return $output;
}
add_filter( 'facetwp_render_output', 'custom_slider_steps', 10, 2 );

Hi,
first of all, thank you for posting this code! :)
I tried to add it to the custom hook plugin, but still it doesn't show any changes in my slider facet.
['YOUR_SLIDER_FACET_NAME'] > I added the label of my slider here.

Do you have any idea? I added screenshots to show what I did.

Thank you,
Lorenzo
