Validate component

[XavierGeerinck]

Should have:

• type
• placeholder
• label
• name
• checkEmail (if true, check if email)
• checkMinLength (specify a length)
• checkMaxLength (specify a length)
• checkRequired (if true, make sure it is not empty)
• ....

This way we can move the validate towards the component itself. Also add a state so that we can specify if it is valid or not.

TODO: How can we check if the form is valid as a whole? (so on submission). Several solutions that I can think of:

• Expose a function is validate in the validateinput to check every component
• Create a custom form component that can do this by a function isValid?
• Go through the states of the methods one by one manually?

I think option 2 is the best and easiest since it removes all clutter and makes for easy submission
