I remember solving this problem before. These are both global components, so you create a single global instance and control them with a global context or function.

You basically have a global part of the component and a local part. The global part is what actually gets rendered when necessary and manages current state, the local part defines what content will be rendered inside the global part for a particular trigger and interacts with the global part when a trigger condition happens (eg hover timeout for a tooltip).

React devs re-discovering DOM manipulation... SMH.

This is, in general, the idea that is being solved by native interaction with the DOM. It stores the graphic, so it doesn't have to be re-instated every time. Gets hidden with "display:none" or something. When it needs to display something, just the content gets swapped and the object gets 'unhidden'.

Good luck.

The post you’re replying to is saying they went FROM always having the component mounted (at least in the component tree if not in the DOM as display:hidden), TO only mounting the component when it needs to be open. They moved from the way you’re talking about, to creating the component/DOM nodes only when needed.

Excessive nodes - hidden or not - cost memory. On midrange Android it’s scarce and even if you’re not pushing against overall device memory limit, the system is more likely to kill your tab in the background if you’ve got a lot going on.
