Tapestry includes the following mixins out-of-the-box.
| Autocomplete | modifies a text field to provide for auto-completion of text using values retrieved from the server as the user types. See instructions. |
| DiscardBody | discards a component's body. Returns false from the BeforeRenderBody phase, which prevents the rendering of the body. |
| FormFieldFocus | instruments the outer Form on which component the focus should be activated. Replaced by OverrideFieldFocus starting in Tapestry 5.4. |
| NotEmpty | attaches to any component that renders an element. At the end of the render, if the element is empty, then a non-breaking space ( ) is injected into the element. |
| OverrideFieldFocus | when attached to a form field, causes that field to gain focus. Starting in Tapestry 5.4, this supersedes FormFieldFocus. |
| RenderClientId | forces a client element to render its client id by ensuring that "getClientId" is called. |
| RenderDisabled | renders an "disabled" attribute if the containing component is disabled |
| RenderInformals | renders out all informal parameters, at the end of the BeginRender phase. This mixin can be used with components that render a single tag inside the BeginRender phase. |
| RenderNotification | triggers event notifications to identify when it enters the BeginRender and AfterRender render phases |
| TriggerFragment | when applied to a Checkbox or Radio component, links the input field and a FormFragment, making the field control the client-side visibility of the FormFragment |
| ZoneRefresh | periodically refreshes a Zone by triggering an event on the server using ajax requests. |
