mhtml file with dropdown list blocked

I am not very familiar with HTML and web development, so sorry for my wording.
I am wondering why I face such an weird situation for me. I want to save a webpage with some form where there are some dropdown lists to choose the answer. The purpose is to make a "screenshot" of that page, but to make possible to see what are the options in the dropdowns.
So my idea is to save a page as a single file .mhtml in Chrome. The questions look like this:
But when I saved the page as .mhtml the file looks like this:
But the main purpose is to see the dropdown list in the file (so in this example list of months).
It nearly works in IE, but the outlook is different. And I am nearly sure that sometimes it doesn't work, but I have no idea why:
Do you have any advice how to workaround that?

Which file the component is stored in

I just landed a new gig with a client with no technical background. They bought a website a while ago and now they want to make changes to it.
The problem is the codebase is bloated with redundant files and I can't seem to reach the exact components that I want to edit.
I tried using React dev tools and it shows the component tree but not which files they are inside.
If there is a way to know which file the component is stored in please let me know. Also, If you have any advice on how to familiarize myself with the codebase fast please feel free to share your experience.
You can click the View source for this element icon.
It will navigate you to source panel of the browser developer tool. You can see the source code of the file and if you Right Click the file, you can get the file path from the dropdown menu.
Since I use webpack, the file path is like this: webpack:///./src/components/sms-code/SmsCode.tsx?5fcf

How to create a UML Class diagram with react JS

I'm newer in Web developpement (I have modest knowledge about it).
I'm asked in my university-project to develop a webapp that generates a UML class diagram using ReactJS.
I've installed nodeJS, webstorm, I tested a "hello world" code, it works but I don't know how to generate this digram, from where start.
In reality, I've tested the library storm-react-diagram, but I didn't get any result.
Please , someone can help me, orient me or propse me any template, any code that works to be inspired. really I'm lost.
Thanks
Try to check mxgraph or jointjs this two libraries will help you in your project also you need to be more clear specifying your project because it depends if you are going to generate the diagrams by using drag and drop method or something else

How to build a simple flash-card website from scratch?

For my personal project, i want to build a simple website where there are questions(cards) and the user can input an answer. There is a list with the cards, which have searchable tags. So, how do i do it? I have tried using template sites, but i don't think they can do it.(since it's interactive)
This is absolutely possible. From a simple google search I came across some code using CSS animations that should get you started:

Now all that's left to do is to generate flashcards based on your data and add previous and next buttons. You're already halfway there!

Can you edit the source code of a google form?

I created a large google form without the script editor. Now I need to duplicate 50 questions, but that is not really possible to do manually. I'd like to edit my form using the script editor.
I tried opening the live form and copying the source code of the form that way, but it's not in the right format to put back into the script editor.
Is it possible to import an existing form into the script editor? Or export the source code of a form at all?
Thanks for the help!
I found the solution - an add-on called Formfuse.
It can:
Create questions from a spreadsheet
Duplicate entire pages of a google form, and put the copies in after whichever page you choose
Convert your form into code
It sounds to me like what you are trying to do goes beyond what Google Forms can do, but looking at the add-ons it appears you can do some importing from the google Sheets program so perhaps you can write out the questions in google sheet and import it.
