# Context objects
Using Context Objects allows to set dynamic context on the Form. Merge Fields from Context Objects can be used everywhere on the Form: as Default Value, Title, Condition and any other input on the Form Item.
## Context panel
The Context Objects and Merge Fields are available on the right side panel.
Select the Context Object Type (1), select required Field (2), Copy the Merge Field value (3) to put it in any place in the form (4).
## Form context objects
Form Source Object
Allows to use merge fields from the form Source Object.
You can also use related object fields but before using you should add them to the Tools - > Fields. See more details at [Additional fields](/forms/form-building/additional-fields.md).
{% hint style="warning" %}
Changes to the Source Object fields are not saved automatically and require using the Save action.
Changes made to the Source Object record outside of the form (ex. changes made to the record on the Salesforce record page) will not take effect on the form until it is refreshed.
{% endhint %}
System
Allows to use System data such as: Date/Time, Session ID, Force Base URL, Force Organization URL.
User
Allows to get the current User information.
{% hint style="warning" %}
Changes made to the User record outside of the form will not take effect on the form until it is refreshed.
{% endhint %}
Form Parameters
Allows to use parameters passed to the form.
The Form Parameters context object is case sensitive.
Variables
Allows to use Variables defined at the Tools -> Variables menu. See more details at [Variables](/forms/form-building/variables.md).
{% hint style="warning" %}
When variables are used to output data on the form (added via the Context Object menu), updates to these variables will not be reflected on the form.
{% endhint %}
{% hint style="warning" %}
When using variables for logic rather than data output (e.g., passing parameters, building list conditions ect), always select them via the built-in Merge Fields picker. This ensures the correct syntax {$Form.$Variables.VariableName} is applied, allowing the system to evaluate the latest variable value at runtime.
{% endhint %}
Parameters
The Parameters context object available on the form Actions. See more detail at [Actions](/forms/form-building/form-action.md) and [Events](/forms/form-building/events.md).
Output
Allows to use output variables returned by [global action and global action group form actions.](/forms/form-building/form-action.md#global-action-and-global-action-group-action-types)
Row
