Thank you very much for the review.

Hello @ohtusabes

If you are allowing selection of only one choice, why do you use a checkbox field instead of a radio button or a dropdown field?

The checkbox field does not include a search box component like dropdowns. However, you can emulate it by using a calculated field as an auxiliary. If you require a custom coding service to filter the checkbox choices based on a calculated field, please do not hesitate to contact us directly via the plugin website. Contact Us.

Please watch the following video. I emulate the process directly in the browser:

Hello @jakubkubajz

Thank you so much for using our plugin.

You can show/hide the “HTML Content” field by selecting a specific choice in the DropDown field by configuring dependencies as described in the following video tutorial:

https://youtu.be/s4FM59LC-H4

However, it does not applies to the submit button.

So, in this case, it is better to use a calculated field as an auxiliary field.

I’ll try to describe the process with an hypothetical example.

Assuming the dropdown field is the fieldname1 and the HTML Content field is the fieldname2, you also want to show the fieldname2 field and hide the submit button if the fieldname1 value is “value A”, and do the opposite for any other fieldname1 value.

Insert a calculated field in the form to be used as an auxiliary (you can hide it from the form and exclude it from the form submission by ticking a pair of checkboxes in its settings), and enter the equation:

(function(){
if(fieldname1 == 'value A') {
   SHOWFIELD(fieldname2|n);
   fbuilderjQuery('.pbSubmit').addClass('hide-strong');
} else {
   HIDEFIELD(fieldname2|n);
   fbuilderjQuery('.pbSubmit').removeClass('hide-strong');
}
})()

Best regards.

Hello @tooni

You are referring to the dependencies that control the behavior of the fields. In addition to showing or hiding fields, these dependencies also activate and deactivate them. When fields are deactivated, they are excluded from the equations and are not included in form submissions. The rules for activating and deactivating fields are triggered by the onchange events of the controlling field, which, in this case, is the dropdown menu.

It’s important to note that the code within your HTML Content field evaluates the equations during the input events. This means that your code is executed before the activation and deactivation rules have taken effect. As a result, when the equations are evaluated, the fields remain deactivated because the necessary activation and deactivation rules have not yet been applied.

Best regards.

Hello @tooni

The problem is simple, and it is caused by your form settings. You disabled the dynamic evaluation of the equations by unticking the “Dynamically evaluate the equations associated with the calculated fields” checkbox in the “Form Settings” tab. Then you emulated the process by entering the following piece of code in an “HTML Content” field:

<script>
fbuilderjQuery(document).on('input', '#fbuilder :input', function(){
if(VALIDFORM(this.form, true)) EVALEQUATIONS(this.form);
});
</script>

This implementation is causing a timing problem. The previous code evaluates the equations before the dependent field is activated.

If you don’t want to enable the dynamic evaluation of the equations, you should edit your code to hear both input and change events:

<script>
fbuilderjQuery(document).on('input change', '#fbuilder :input', function(){
if(VALIDFORM(this.form, true)) EVALEQUATIONS(this.form);
});
</script>

Best regards.

Hello @ohtusabes

Yes, that’s possible, but it requires the DS fields distributed with the Developer and Platinum plugin distributions.

You can insert a DS field in the form, select the logged-in user information as its data source, and retrieve the preferred user details (ID, email, first name, last name, login, etc.)

You can even send a copy of the data to the logged-in user email.

Best regards.
