react-fit
Advanced tools
Readme
A component that aligns its child relatively to its parent while being aware where it may and may not fit.
npm install react-fit
or yarn add react-fit
.import Fit from 'react-fit'
.function ElementWithChild() {
return (
<Parent>
<Fit>
<PopoverChild />
</Fit>
</Parent>
);
}
Your project needs to use React 16.8 or later.
Add React-Fit to your project by executing npm install react-fit
or yarn add react-fit
.
<Fit />
as a child is displayed below its parent, aligned to the left.<Fit />
checks if there's more space for the element on the other side(s) of the axis/axes the collision(s) has been detected on. If so, the element is moved above its parent and/or aligned to the right, depending on the collision axis.<Fit />
decreases the element's size. If min-width
/min-height
are provided, they will be respected.By default, the element is displayed below its parent, aligned to the left of its parent.

)By providing mainAxis="x"
to <Fit />
, the element is displayed on the right of its parent, aligned to the top of its parent.

If you wish to change this spacing, you can provide spacing
to <Fit />
. For example, if you wish for the child to touch the borders of the container, decrease the spacing by providing spacing={0}
to <Fit />
.

└─┴─────────────────────────┴──────────────┘
You can also provide different spacing for each side by providing an object, for example spacing={{ top: 10, bottom: 20, left: 30, right: 40 }}
, to <Fit />
. Note: Memoize the object or define it outside render function to avoid unnecessary re-renders.
To avoid unnecessary style recalculations that may be caused by React-Fit applying the styles needed to make it work properly, the element should have absolute position, and its parent element should have relative or absolute position.
