Configuration information that is attached to this component. This information is not functionally used by CaptainCasa, but may be used for any application specific purpose.
Description of object that can be dragged from this component. The description consists out of a type and and id. A component may have multiple objects that can be associated.

By default a border is drawn aroudn a focussed element. This can be switched off by setting this attribute to false.
| true | Draw border when focussed (default) |
| false | No border when focussed |
Height of the control. Either defined as absolute value or as percentage value. Pay attention when using percentage sizing: the size refers to what is given from the components above. - When using components within a grid (FIXGRID) then the sizing of the component is completely managed by the grid, you do not need to specify any height in this case.
| 100 | 100 Pixels |
| 120 | 120 Pixels |
| 200 | 200 Pixels |
| 50% | 50 percents |

Client side event that triggers a server invoke.
| click | Mouse click (both mouse buttons) |
| leftclick | Mouse click (left mouse button) |
| rightclick | Mouse click (right mouse button) |

Reference to the id of a POPUPMENU definition that is available either in this page or in a page that includes this page.
If set to true, then an explicit roundtrip is triggered when the user presses the right mouse button in order to open a popup menu. As result you can define the popup menu dynamically (using DYNAMICCONTENT) and prepare the popup menu at this point of time when the user want to open it.
| false | Menu is already defined in layout, no roundtrip (default) |
| true | Menu is dynamically created, roundtrip is triggered |

| ref | One reference |
| ref1;ref2 | Two references |
| ref1;ref2;ref3 | Three references |

| bottom | Bottom |
In CaptainCasa you can define styles definitions for components. A style definition is a definition of a set of default attribute values that are applied to the component. In case you want to differenciate between different usage types of the component you can apply multiple styles - and use the stylevariant attribute to select between.
Trigger value: if the value changes then the component's activity is executed on client side. Use class Trigger on server side for implementations of this property.
Vertical positioning of the content within the row.
| top | Top |
| middle | Middle (default) |
| bottom | Bottom |
Width of the control. Either defined as absolute value or as percentage value. Pay attention when using percentage sizing: the size refers to what is given from the components above. - When using components within a grid (FIXGRID) then the sizing of the component is completely managed by the grid, you do not need to specify any width in this case.
| 100 | 100 Pixels |
| 120 | 120 Pixels |
