Dropdown menu gets cut off in "slider-parallax-inner"

Hello,

I put a dropdown menu which has a longer height of the slider with css="slider-parallax-inner" but the drop down menu gets cut off.
I want the dropdown menu on top of the slider so that it shows all of the dropdown menus without getting cut off at the bottom(Please see the attached). I tried making some changes with z-index but the drop down menus was on the top but of all elements but it displayed even after the slider has gone above.

What should I do if I want the dropdown menu on top of the slider not to get cut off and ,at the same time, it will disappear when scrolling above.

please advise me.

Thank you in advance.

Hello,

I need your help with 2 things as below:

1. Select box was cut in slider-parallax with class="slider-parallax-inner". I have tried giving z-index but it didn't work.
Would you please take a look at the following url and the attached image.

2. "data-dark-logo" for switching two logo images doesn't work and it only shows

image both on the slider and on the top when scrolling-down.

Please advise me.

I really appreciate your great support as always.
