'How to get a value using formik with a MUI component?
I am using Formik in order to submit an array of components using MUI sliders.
I have created a slider component using the MUI library. You can see that in the code below in the declaration of:
import SliderSchedule from ....
So, I searched an example and I found a way to create and delete components and I copy from them. However now I want to also submit the result. But when I click the button I get no values.
As you can see I have the Comp1 that I declare the array const [sliderSchedule, setSliderSchedule]. Which has to contain values like: [(100, 200), (150, 300), (400, 700), ...]. Then I have the two function addHandeler and deleteHandeler that creates and deletes the components. This works fine.
Then we have the formik and that's the last thing that I have implemented after creating the the Comp2 that it's the "component" that we are creating with the addHandeler and deleteHandeler which creates the slider and a button to eliminate:
As you can see is very simple. And it works fine. But then when I click submit I get no values:
Thank you in advance.
