Good time

In Joomla 3.7 there are some problems with class customization.
A field in Joomla 3.7 has three parts for display.
Input field and field-tag and field-value
When you assign a field to a specific class in the settings, this class only affects the field-entry field. This means that you can not customize the field-label and field-value appearance for your field. To resolve this issue, there are two other parts in the field's settings to be defined in each field we create separately defined for field-label and field-value class.

Another problem is that the Plugin does not include the field in Joomla 3.7. It does not know the class's dedicated field and the general settings class. This means that it will be different for a custom field class. The appearance of a field that differs initially or at the end of the content with the appearance of a field that is different from the content of the plugin.

There is also a third problem, and it can not completely disable the default view of the content field, and only use the plugin to insert the field in the article to display the fields. It is better to display the default view of Joomla! 3.7 fields in addition to the top and bottom options (no). This will be useful for when we want to temporarily disable the display of fields in a post or only use the plug-in to display the content.

is this #15667 something that may help you?

Although I'm not able to read English well, I suppose I have similarities with what I said.

What I definitely know is that in updating Joomla, three things have to be added to resolve this issue.
1- Provides the ability to define separate classes for three field-entry fields, field-label and field-value for each field specifically.
2- Follow the plugin to enter the field in the post from the dedicated classes of each field if specified.
3- Possibility of not displaying the fields of a content.

Of course, adding two filter plugins and comparing two or more field fields can complete and complete this collection.

3- Possibility of not displaying the fields of a content.

This is already possible. Set automatic display to No

thank you
I hope that with the addition of the rest of the cases, the power of this component will increase.

excuse me
Are you a Joomla project developer yourself?
Can we hope that these happen in the next updates?

Thank you.
But I still did not receive a clear answer from you to solve my problem.
Please give me the code you need to resolve this issue if I may add my Joomla!
Thank.
