The below table represents all the available panel properties and the corresponding functionalities

PanelObject Description

row Specifies the row value in which the panel to be placed.
col Specifies the column value in which the panel to be placed.
sizeX Specifies the width of the panel in cells count.
sizeY Specifies the height of the panel in cells count.
minSizeX Specifies the minimum width of the panel in cells count.
minSizeY Specifies the minimum height of the panel in cells count.
maxSizeX Specifies the maximum width of the panel in cells count.
maxSizeY Specifies the maximum height of the panel in cells count.
header Specifies the header template of the panel.
content Specifies the content template of the panel.
cssClass Specifies the CSS class name that can be appended with each panel element.

Positioning of panels

The panels within the layout can be easily positioned or ordered using the row and col properties of the panels. Positioning of panels will be beneficial to represent the data in any desired order.

The following sample demonstrates the positioning of panels within the dashboard layout using the row and column properties of the panels.

Sizing of panels

A panel’s size can be varied easily by defining the sizeX and sizeY properties. The sizeX property defines the width and the sizeY property defines height of a panel in cells count. These properties are helpful in designing a dashboard, where the content of each panel may vary in size.

The following sample demonstrates the sizing of panels within the dashboard layout using the sizeX and sizeY properties of the panels.
