I've written and optimized a Shiny app, and now I'm struggling with the IT section of the organization where I work to have it published on their servers. Currently, they are claiming that the app is not W3C compliant, which is true, according to the W3C validator.

The errors I'm trying to solve, with no success, are:

• Bad value “complementary” for attribute “role” on element “form”.

• The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.

Such errors can be seen also in very minimal shiny apps, like:

So, I'm working on a simple kivy app and I have three buttons (MDRaisedButton's) which each open the same KivyMD Menu (MDDropdownMenu) on release.

1. Two of these buttons are in different ScreenManager screens.

2. The other button is in a GridLayout in the Screen outside the ScreenManager.

When I open the menu using the buttons inside of the ScreenManager, the menu appears at the button that is outside of the ScreenManager, no matter which button I press.

So how can I change the caller, or the position of the menu when it appears to be that of the buttons in my ScreenManager screens?

Me clicking on the button inside the ScreenManager screen:

The menu appears on the wrong button:

I am using AvForm in React js. I want to reset the form after form Submission. But I am unable to reset the code unless I refresh the whole page. Whenever the form submits it retains the old value but not reset the fields

form.js

New Rails 7 app created in 2021 or 2022, when I click on a form with data-turbo-confirm, the alert message does not show.

My chart y labels are cut off and by trying different solution found on stackoverflow like adding spaces in labels or setting layout padding did not solved the problem.

[Editing this question completely] Thank you , for those who helped in building the Periodic Table successfully . As I completed it , I tried to link it with another of my project E-Search , which acts like Google and fetches answers , except that it will fetch me the data of the Periodic Table .

But , I got a problem - not with the searching but with the layout . I'm trying to layout the x-scrollbar in my canvas which will display results regarding the search . However , it is not properly done . Can anyone please help ?

Below here is my code :

There are lots of data coming from multiple sources that I need to group based on priority, but the data quality from those sources is different - they may be missing some data. The task is to group that data into a separate table, in as complete as possible way.

For example:

I am querying an API to get an image as response. I would like to show the image when the state is updated. Another problem is that when I don't have the image, I always get printed the icon of image, and I don't want that. I tryied to solve this problem with this code, but I still can't manage to have the behaviour I want.

To be more clear, I want that, when the form is submitted, I get a response with an image. I update the state with setImage, and I want the image to be plotted on the page.
