I created my shiny dashboard sidebar like this I linked MenuItem to tabItem, by tabName and in each tabItem I put tabsetPanel

I would like, when I choose group A, to be able to display the different panels that are the subgroups A1, A2, and A3. I would like to do the same for group B and its subgroups. I can't do it, because only the panels in group B are displayed. I would like to keep this dashboardSidebar architecture.

Here are below my scripts

I am learning about image pyramids by following the official Python tutorials here.

I get the following error as well as a warning that highlights the one-before-the-last ref to cols.

Can someone please help me understand what the error is caused by and how I can change the code to resolve the warning on real = np.hstack((A[:, :cols/2], B[:, cols/2:]))?

so I'm having a bit of an issue here. I'm trying to do something that in theory should be very simple, but for some reason it's just not working.

I'm trying to get a Javascript function to reset a HTML form whenever a certain button is clicked.

Here is the form HTML code:

This might get a bit tricky to wrap your head around but here goes nothing:

I have class(es) that renders a component, and they use a function inside the class(es). Why not a method you might ask, because I need this method to be accessable by other classes. However each function is Class specific, which is why I can't make a generic helper function that is global.

Here is an example

I am trying to apply a pound sign to my data - this is my code:

I'm not sure if I'm missing something and that might make this question very stupid. But I can't understand why the hell it's failing after trying pretty much every approach one could have.

So, super simple, I have this GLib Tree and I want to insert stuff into it in other functions. Why none of the options presented below work? I can understand the first failing more than the second to be completely honest.

I am trying to find all fullstops in a body of text and create a whitespace in from of them. I am only allowed to use for loops or I would use regular expression. I can't understand why the following for-loop does not replace the original letter with my new assignment. My code is as follows:

I'm writing a test using tsung extended by erlang modules, but I always get the same error and don't even send anything to the server.

the error is:

What's the right approach to have dynamic/conditional filtering in shiny inputs (selectizeInput) where multiple = TRUE?

In this example I'm trying to show parent filters limited by the grandparent filter (any, all, none), and then child filters limited by the parent filter.
