customSelect | jQuery UI widget to pretty up select elements | Frontend Framework library

I am using a material ui select component, which is filled with data from an array with values and options.

In array there is also nested object prop called "setFilter". setFilter has a value of setState, which will be later used in handleFlilter.

There's a project I am working on. I have a challenge in implementing something.

I have four arrows to show the progress of a form which is Active-Next-Inactive-Completed. Each state should be distinguished using different colours on the arrows.

Then when one clicks on a button after filling each form, the person will be taken to next page and arrow state should change too.

I have designed the arrows, created the css styles, the button clicks takes to next page but my challenge is to make the arrows to change too at the same time. Image

I am having problems with updating state by mergin selected input props in one string in order to pass a proper path with values to API.

I just launched my store on wordpress and I ran into a problem: When I am on the home page of the site, all my product titles are in H2 and should be in h3 (SEO reasons), my recommendation products are also in h2 instead of h3 (on the single product page and in collections, i would like to change them all to h3). I looked for a long time where the problem could come from, searched all the files of the theme to change any title from h2 to h3 but nothing helped, I can't find where it is! I also asked the theme creators for help but they told me it was woocomerce's fault and there was nothing they could do ..

A lot of people have had some of the same problem under other themes but they don't have the same "function.php" as me. I also followed this: How can I change the product

Can someone help me on this problem ?

here is my "function.php" but i dont think it'll help..

I know this has been asked for regular html controls, but I cannot seem to get rid of this ugly black border that surrounds my selectpicker list box :

And when I don't have focus:

There's already a focus radius blue color that surrounds my input, so for accessibility, I do not need this black one. I've read everywhere that I need to use outline: none; css, but it isn't working in my case.

This is my CSS:

I have the following form:

I am passing array as a prop to another component, and when I want to read this on mounted in that component, I got Proxy {}. How to read data from this prop? You can see in example when I want to console log prop, result is Proxy {}. I can see all values in HTML structure, but not in the console on mounted.
