# Using the Standard VDL Components with Progress Updates

Once the view can display custom VDL during execution, it is possible to also use other VDL components that will display useful information about model progress.
Any VDL component that takes the name of an entity can use a progress entity that has been defined in the model. A VDL Field can display a scalar value, so you would want to

    <vdl-field value="=scenario.entities.PROGRESS_SCALAR.value"></vdl-field>

set the 'enabled' attribute to false. Alternatively, it is possible to use an expression and a VDL Var to set the value of the vdl-field.
If there are progress entities of array type in the model then you can use these easily with <vdl-table> and <vdl-chart>:

    <vdl-table>
    		<vdl-table-column entity="PROGRESS_ARRAY"></vdl-table-column>
    </vdl-table>

This works the same for input and result entities. As the model updates this array with progress data then the table (or chart) will update accordingly.
Lastly, any of the VDL attributes (such as vdl-text, vdl-if, or vdl-repeat) can react to progress updates.

    <span vdl-text="=scenario.entities.PROGRESS_SCALAR.value + '%'"></span>
