I am trying to detect that a device is mobile in order to render the screen differently. We have a 4 column grid layout on desktop and want to display only 1 or 2 columns if the device is mobile.

Im pretty new to programming and im trying to develop a chrome extension. The website that im trying to manipulate has a div element and within this div are multiple divs and the number of these divs vary depending on the scale of the first div and the scale is draggable by the user.

I'm trying to implement a highChart using react and react-grid-layout. The chart should resize according to the react-grid-layout and for that, I need to pass chart.reflow() in the onResizeStop prop of ResponsiveGridLayout.

Thanks!

I am trying to delete an item in React by clicking on a button. Currently my code returns Cannot read properties of undefined (reading 'ProductID') and I am not sure why since I am accessing it via an id and it should work.
