The situation is a bit complicated:
inside a component called "LeftSectionHeader" I have a div, which when clicked must render a component;
the component to be rendered is called "ProfileMenu", and is basically a div that must be rendered on top of "LeftSectionHeader" itself and another div;
All these components are rendered inside another component called "Main".
The problem is that if I define the function inside "LeftSectionHeader", "ProfileMenu" will be rendered inside, while I need it to not only be rendered outside, but even cover it; that's why you'll see some boolean vars inside "Main", because that is the only way i could render it, but it still doesn't cover the other divs. I'll attach the code of each component and how the final result should look below.
LeftSctionHeader:
function LeftSectionHeader(){
return(
<div class="left-section-header">
<div class="crop" ><img src="./images/profiles/anonimous.png" /></div>
</div>
);
}
The div belonging to the "crop" class is the one that must be clicked to render "ProfileMenu"
ProfileMenu:
function ProfileMenu(){
return(
<div class="profile-side-menu">
//A lot of boring stuff
</div>
);
}
There are some functions related to this component, but they are not important, so I didn't put them, just ignore it
Main:
var p=true;
var m=true;
function Main(){
return(
<div class="main">
<Header />
<div class="left-section">
{m ? <div><LeftSectionHeader /><LangMenu /></div> : <ProfileMenu />}
</div>
{p ? <PostPage /> : <NoPostsMessage />} //Ignore this line
</div>
);
}
This might help as guidline, hopefully!
function LeftSectionHeader({ onClick }){ return( <div class="left-section-header" onClick={onClick}> <div class="crop" ><img src="./images/profiles/anonimous.png" /></div> </div> ); } function Main(){ const [showProfile, setShowProfile] = useState(false); return( <div class="main"> <Header /> <div class="left-section"> {!showProfile ? ( <div> <LeftSectionHeader onClick={() => setShowProfile(true)} /> <LangMenu /> </div> ) : <ProfileMenu />} </div> {p ? <PostPage /> : <NoPostsMessage />} //Ignore this line </div> ); }
The simplest solution might be to pass a handler into the header component to toggle the menu:
function App () {
const [showMenu, setShowMenu] = useState();
return (
<div>
<Header onMenuToggle={() => setShowMenu(!showMenu)} />
{ showMenu && <Menu /> }
</div>
)
}
function Header ({ onMenuToggle }) {
<div onClick={onMenuToggle}>...</div>
}
Caveat: This will cause the entire App component to re-render when the menu state changes. You can mitigate this by either
Another approach would be to leave the state handling in the LeftSectionHeader component and then use a React portal to render the menu elsewhere in the DOM.
