Can anyone help me, I'm trying to make a react table, but it says that the element type is invalid.

React table is now headless, which means you have to define the HTML structure and it only provides the logic using hooks. If you want the old fashioned react table, use react-table-v6 instead.

I use quill editor. After i add this using react-html-parser. But this give me warning. How to fix it?
Warning: A component is contentEditable and contains children
managed by React. It is now your responsibility to guarantee that none
of those nodes are unexpectedly modified or duplicated. This is
probably not intentional.
Currently I have to do the following:
interface MyCompProps {
someAttr: number
}
I want to use aria-, and then I have to list upfront all aria-* I need. Furthermore, I can't set a simple className on the component. How can I avoid this, i.e. allow normal HTML attributes on component? Or is it a bad practice? I'm skimming the Advanced Guides on reactjs website and nowhere mention that this is a bad practice, so I think it is acceptable.
Note that all aria-* HTML attributes are fully supported in JSX. Whereas most DOM properties and attributes in React are camelCased, these attributes should be hyphen-cased (also known as kebab-case, lisp-case, etc) as they are in plain HTML

I have a Ant Design 4.x.x Form element without multiple Form.Item. I need to implement some logic involving form items' values, for example disabling a field if another one's value equals something, or recalculate select options when a text input changes.
To do so, I create the form using Form.useForm() and use form.getFieldValue() in my functional component body and / or in the returned JSX, like so :
It is working as I expect to, but at startup, getFieldValue usages throw annoying
index.js:1 Warning: Instance created by `useForm` is not connect to any Form element. Forget to pass `form` prop?
I found that Form functions cannot be used before rendering, and the problem also occured when displaying a form in a Modal like stated in the docs.
So I feel that I'm missing something on how to correctly add custom logic between fields, or doing some calculation involving fields values in component body.
What would be a correct approach to do this ?
Try adding getContainer={false}, to your modal this will work for you.
I'm making a react app using antd, I'm trying to add modal but it doesn't work, every time I click the trigger button I got errors saying "Uncaught Error: Element ref was specified as a string (header) but no owner was set. You may have multiple copies of React loaded.". Im following this syntax from https://ant.design/components/modal/
I found related problem https://github.com/jrm2k6/react-markdown-editor/issues/55
and according to react
https://reactjs.org/docs/refs-and-the-dom.html#legacy-api-string-refs
they dont recommend using ref attribute, instead use a callback pattern.
I dont know what to do..
Any help, thanks.
How do I use the Multiselect of React Widgets in Redux Form where I can allow the creation of new option as well which will be stored with redux form state. Redux form documentation do not have example with new tag creation option.
I got the solution, we need to make allowCreate={true} with onCreate={(name) => this.input.push(name)} both the attributes are necessary for the create tag option to appear.
I've never used this package yet, but I don't think the package provides a functionality to allow tag creation as it is.
Either you should implement it yourself, by providing an input for option creation and push them in to your options state object or you use another package like https://github.com/JedWatson/react-select which already implemented the desired functionality.
I think you mean onCreate={(name)=>data.push(name)} because this.input doesn't contain push method.
