how do I fix readonly <input>, please?

I'm very new to react, this is the first react code I've ever written but I've decades experience in other technologies.

I'm using the html tag to enter data and sometimes it's read/write and sometimes it readonly, that is a problem I need them to always be read/write.

I've found a post on stackover which tell me what is causing the problem but it doesn't explain how to fix the problem. This link https://stackoverflow.com/questions/28315205/why-does-react-make-inputtype-text-fields-readonly-unless-i-supply-onchange

So in my code you can see I've two 's that work, they point to the attributes theXXX and theYYY. However I have an array that is called lstXXXs in my attributes and I display this array, see the line beginning with const htmlLstXXXs = props.attributes.lstXXXs.map

Basically because I have the two variables theXXX and theYYY working I was hoping to copy the same method for updating the array, but whatever I try to do it just won't work, the are readonly.

My function to update the array works, but the 's being readonly is the problem.

Does anyone have any idea how I can fix it so that all my 's tags are read/write?
