Didn't work with toggle type. Tired a lot but still no luck.

Same problem as CA-Irag

Works well with checkboxes, but $wp_customize->add_setting must have 'transport' => 'postMessage' setting instead of the default 'transport' => 'refresh'

Detailed here: https://codex.wordpress.org/Theme_Customization_API#Part_3:_Configure_Live_Preview_.28Optional.29

I would like to keep the refresh option. Would there be any possibility?

@CA-Irag and others who have faced the same problem is because of the lack of server side active_callback for the control. This jQuery only makes active/inactive on real time front end HTML. You also need to setup a active_callback for the desired control.

Here is more details on it - https://make.xwp.co/2016/07/24/dependently-contextual-customizer-controls/

Works once, then, when Customizer get refresh, the control appear again. Don't know how to solve this.

Found the solution, instead of use the method deactivate and activate, use toggle like this:

wp.customize.control('my_control', function (control) {

    const toggleControl = (value) => {

        if (condition) {
            wp.customize.control('control_to_hide').toggle(true);
        } else {
            wp.customize.control('control_to_hide').toggle(false);
        }
    };

    toggleControl(control.setting.get());
    control.setting.bind(toggleControl);
});

    toggleControl(control.setting.get());
    control.setting.bind(toggleControl);
});

condition undefined?

@lwxbr Cheers that worked!
