‍

‍

This article explains the Signature block that can be added as a block to design an app.

Used For

1. Capturing signatures.
2. Signing forms, contracts, etc.
3. Signing receipts.

‍

Editing the Block

Click on the block and start editing on the panel that appears on the right side.

‍

‍

Label

This is what appears as the name of the input block to the end-user.

Description

This is the text that goes below the input block to help the user.

Changing the signature

By default, users can edit the signature. If you don't want users to modify the signature, turn off the option "Allow Signature to be changed by user".

Required

Tick this option if you want the user to compulsorily sign the form.

Automatic Draft Saving During Signature Capture

When users fill out a form, they normally need to click Save Draft to save their progress.

However, if the form contains a Signature block, the form is automatically saved as a draft when a signature is added. The draft is also updated if the signature is cleared. Along with the signature changes, all the information entered in the other fields up to that point is also saved in the draft.

Changing the value of other fields does not automatically save the draft. Automatic draft saving is triggered only when a signature is added or cleared from the Signature block.

This behaviour is supported on both the web app and the Clappia mobile app.

If the Save Draft option is disabled for the app, automatic draft saving will not occur.

‍

Advanced Options

Use this option to show the advanced options to configure the counter block.

‍

‍Display this field if

Use this if you want to show or hide a field under certain conditions. It accepts the standard Clappia Formulae, similar to conditional sections.

1. You can type ‘@’ to get a list of all the variables in the app and select variables.
2. Using these variables you can write Excel-like formulae.

Advanced Label

The Advanced Label option allows you to change the label of a field dynamically based on a condition you define. Instead of always showing the same fixed label under the ‘Basic’ tab, the field can display different labels depending on requirements of the form. Use spreadsheet-like functions such as IF, AND, OR, etc. and make use of other field variables to set your conditions. Type @ and select the field.

This is useful when the meaning of a field changes based on context, business logic, or user choices.

For example:
If your dropdown named Role includes options “Customer” and “Technician”.
Your signature block label should reflect who is expected to sign.

So:
– If Customer, show “Customer Signature”
– If Technician, show “Technician Signature”

Formula:

This allows the same field to adapt its displayed purpose without needing multiple separate fields.

‍

Advanced Description

The Advanced Description option works exactly like Advanced Label, but it changes the description text instead. This is useful when guidance or instructions for a field need to change depending on earlier answers.

For example, using the same scenario from Advanced Label:
If you have a dropdown called Role with options like “Customer” and “Technician”, you may want the description of your Signature field to guide the user differently depending on what they selected.

So:
– If the user selects Customer, the description could say: “Customer must sign to confirm receipt or acceptance.”
– If the user selects Technician, the description could say: “Technician must sign to confirm work completion.”

Formula:

This helps users understand what is required from them without showing unnecessarily long or irrelevant instructions.

‍

Additional Examples (Apply to Both Advanced Label and Advanced Description)

1. Showing nothing until a selection is made

For example, if you have a dropdown field called Visit Category with options “Routine” and “Urgent”, you may want the label or description of a field to remain blank until the user first selects a category.

Once a selection is made:

• If the user chooses Routine, the field will display “Routine”.
• If the user chooses Urgent, the field will display “Urgent”.

Formula (can be used in either Advanced Label or Advanced Description):

The label/description stays empty until the dropdown has a selected value.
After the user picks an option, the selected text (Routine or Urgent) becomes the label or description.

2. Changing label/description based on language selection

For example, if your form includes a dropdown field called Select Language with options English, Spanish, and French, you can show the label or description in the selected language.

So:

• If the user selects English, show English text.
• If the user selects Spanish, show Spanish text.
• If the user selects French, show French text.

Formula (can be used in either Advanced Label or Advanced Description):

The formula returns the text for the selected language.
Only one label/description is shown at a time, depending on what the user picks in the Select Language dropdown.

Important Notes (applies to both Advanced Label and Advanced Description)

1. Variables do not change
When a field is created, its variable name is derived from the label you set in the Basic tab. That variable name is what you must use in formulas, workflows, and other logic. The visible label or description shown by Advanced Label / Advanced Description does not change the variable name.

2. Submissions tab: table view vs right panel
In the Submissions area, the table view always displays the labels from the Basic tab. When you open an individual submission, the right panel shows the labels and descriptions as they appear in the form (i.e., the Advanced Label and Advanced Description applied for that submission). This keeps the submission list consistent while letting reviewers see the context-aware labels and descriptions when viewing a record.

3. Bulk Edit shows Basic tab labels and descriptions
When you need to Bulk Edit submissions, the spreadsheet you download shows the labels and descriptions from the Basic tab only. Advanced Label and Advanced Description are not applied in Bulk Edit, so keep that in mind when preparing bulk updates.

4. Some fields cannot be used inside Advanced Label/Description formulas
Certain block types do not expose a variable that can be referenced in Advanced Label or Advanced Description. If a block does not expose a variable, you cannot use it inside the formula.
