# Master Mapping

We'll start by creating a master form first where we would map the values.

In the basic details under ***'**Apply master data settings',* turn on *'Use form submissions as master data for other forms'.*

The master form would have 3 select type fields **Purchase Type, Item Name** & **Item Price.** 

<table data-header-hidden><thead><tr><th width="179.12212802630438"></th><th width="229.92385819085092" align="center"></th><th align="right"></th></tr></thead><tbody><tr><td>Purchase Type</td><td align="center">Gadgets, Stationery, Pantry</td><td align="right">Price</td></tr><tr><td>Gadgets</td><td align="center">Mouse, Keyboard, Monitor</td><td align="right">450, 650, 1200</td></tr><tr><td>Stationery</td><td align="center">Pen, A4 Sheets</td><td align="right">200, 450</td></tr><tr><td>Pantry</td><td align="center">Coffee, Muffins</td><td align="right">200, 300</td></tr></tbody></table>

**Onc**e the options have been added go to **Settings > Conditions > Conditional value of fields** and map the data as per the table above.&#x20;

Now we'll make the child form with similar fields.

Create another form with the select fields **Purchase Type, Item Name & Item Price** and a text field **Employee Name.**&#x20;

Once we've made the form we'll pick master for the fields separately.

* Click the **settings** icon next to the select fields and open **Master data settings**.
* **Toggle on** *'I want to pick master for this field separately'.*
* Select the master form we made previously.
* ***'Select the master field from which value should be populate'***

Similarly select master for the remaining two fields **Item Name** & **Item Price**.

Last step of the process would be adding conditional settings in this form.

Just like the master form, we'll map **Purchase Type** with **Item Name** and **Item Name** with **Item Price**.&#x20;

Here's how it would look like to the end user.

As per the data in the master form, options would populate the select fields.
