A fieldset container component that groups related form fields with a legend/header and optional collapse functionality. RadzenFieldset provides semantic form grouping with visual borders, useful for organizing complex forms into logical sections. Fieldsets are HTML form elements that semantically group related inputs, improving form structure and accessibility. Features visual and semantic grouping of related form fields, customizable header via Text or HeaderTemplate, optional expand/collapse to hide/show grouped fields, optional icon in the legend, optional summary content shown when collapsed, and screen reader announcement of fieldset legends for grouped fields. Use to organize forms into sections like "Personal Information", "Address", "Payment Details". When AllowCollapse is enabled, users can collapse sections they don't need to see.
