Show/hide field based on selection

[Valhuh]

Hello,

I am not an expert in JS/CSS but I am learning step by step. I have a list in SharePoint with a choice type of field and 3 options.
When selecting one option, a single line text field should appear below.
Listofoptions --> Option 1 --> Show Field 1, hide Field 2 and hide field 3

Can anyone help me writing the script?

Many thanks.
Valerie

Sure, we can definitely help you! Just tell us the type of your choice field - is it a dropdown menu, radio buttons or checkboxes?
