SideBar | 全新的快速索引导航栏，联系人字母排序侧边栏。

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:

I have a sidebar that contains 2 panes. When I resize the window vertically, I want the top pane to dynamically resize, and the bottom pane to remain to a fixed size. When the total height of the sidebar is smaller than both panes, I want the top pane to shrink smaller than it's content, and become scrollable.

The expected behavior is the same as VS Code's sidebar.

Currently, when resizing, the top pane "pushes" the bottom pane down.

I'm getting this warning in React app:

I have been experimenting with full responsive layouts between desktops, tablet, and mobile phone sizes for a bit but am having trouble with the layout below.

I was using a grid layout from bootstrap but since it is two columns, as the width shrinks, the second column of two goes below the left, main content section. I want to split it up as the screen caps below state.

This is the starting view:

This is what I want to happen:

This would be the mobile phone view:

So the wide view will get shrunk during testing and I want it to jump to the mobile view where the top side bar goes above the main content and matches the width of the main content while the bottom sidebar does the same thing to the bottom.

It is easy to put both sidebars on the bottom but I want to try to figure out the possibility of splitting it up.

For testing I am using flexbox, css3 and bootstrap5+ and no plugins or javascript.

I am making a book via bookdown. I know it is possible to omit headings from the Table of Contents by adding the attributes {.unlisted .unnumbered}, as shown in Section 4.18 of the R Markdown Cookbook. However, how can I add arbitrary content to the Table of Contents? If I only needed to add this for the PDF output, I could use (e.g.) the LaTeX command \addcontentsline, but I need this to show in the HTML contents sidebar as well.

For example, if you set up a new default bookdown project from RStudio, it includes the file 01-intro.Rmd. The first few lines are

I have an master detail app in iPad, and when run the app in portrait mode the sidebar is hidden. I need to push Back button to open the sidebar.

Can anyone help me to show the sidebar by default? I found an answer that suggest to use StackNavigationViewStyle when the app is in portrait, but then the app seems like a giant iPhone and dissapears the master class like a sidebar to appear like a view.

Thats my code.

I want to add my Google Workspace Marketplace Add-On to app launcher but it is only appearing in the sidebar. I have gone through the support documents but have not found anything in this regard. How do I make it appear on the application launcher as well?

The app launcher image is given below

The sidebar icon is shown below

EDIT TO ADD DETAILS

The application must be started with a page with a form, enter email and password and when Login takes us to the menu screen, which I show in the screenshot. However, when I enter the email and password, the application does not move. The log works, because a consolelog() shows it to me

It's the second screenshot

I do not understand what I have wrong. Now I show the modified App.js file to show the form, but when I register, the application does not reach the Menu, page

I am trying to create an admin panel and in which I have a sidebar menu. I have created a dropdown menu and it's working using the useState hook but not working as I wanted. What I wanted is when I click on Clients so if statement should only run for its children only not for all sibling children.
