Choosing a subset from a long list is easiest with two lists and buttons to move items between them.
Why it helps
- Two lists, clear movement
- Good for long lists
- Simple to understand
Where it fits
- Assigning users to a role
- Choosing columns
- Picking products
Example
<TransferList TItem="string" Items="_roles" @bind-Values="_chosen" Label="Roles" />
<span>Chosen: @(_chosen.Count == 0 ? "none" : string.Join(", ", _chosen))</span>
@code {
private readonly string[] _roles = ["Reader", "Editor", "Reviewer", "Publisher", "Administrator", "Auditor"];
private IReadOnlyCollection<string> _chosen = new List<string> { "Reader" };
