FAQ

Why Input lose focus when change prefix/suffix

When Input dynamic add or remove prefix/suffix will make React recreate the dom structure and new input will be not focused. You can set an empty <span /> element to keep the dom structure:

const suffix = condition ? <Icon type="smile" /> : <span />;

<Input suffix={suffix} />;
