After several attempts to operate a conditional field on item form, the formula still invalid.
The use case is the following one:
The same tests are performed by replacing '==' by '=' and by removing the simple quote around true & false
The conditional formula is not functional currently or something is wrong?

@Laurent SITTLER As far I have tested this function only works in the display form not in Edit or New Form. Even they don't allow to save the formula as real time evaluation of fields are not happening.
See the below screen shots: 1. New Form:
2. In Display form It works:
3.Finally Display Form formula:
But you can use power-apps that will give you this feature. If I could help to find the solution, please like or mark the answer as solution.

Hi @Laurent SITTLER , @Vikram_Samal has a good idea on the Power Apps form to show/hide. Here's a great article from Nate Chamberlain on how to accomplish this: https://natechamberlain.com/2019/07/18/show-hide-fields-conditionally-in-powerapps-forms-based-on-dr...

For example, Region selection, I want to show/hide Finished Goods Notification column
1) Condition: if Region = US, hide Finished Goods Notification else show
2) Click on edit item, change the region to US.
3) Then click save in save form.
4) Open the form and Display mode, see below screenshot Finished Goods gets hidden.
5) then open the form in Edit mode, here also Finished Goods Notification column is hidden.
6) I wrote the formula on Finished Goods Notification column as below:

@Laurent SITTLER : Of course PowerApps is the ultimate solution to design form and apply formulas.

@Vikram_Samal : Its working for me on Edit and Display form as per the steps mentioned by me in earlier screenshots.
As per the microsoft standard step mentioned in the link also given by the @Laurent SITTLER ----> https://docs.microsoft.com/en-us/sharepoint/dev/declarative-customization/list-form-conditional-show...
Note: Check the second step, it says Open an item to view the item details in the display form.
So in order to imbibe the formula you have to follow as per given standard steps.
To show or hide a column in a list or library form:
Go to the list or library for which you want to show or hide columns in the form.
If you are in a list:
If you are in a document library:
At the top of the form, select Edit Form > Edit columns.
In the Edit columns pane, check (to show) or uncheck (to hide) the box for the column or columns as needed.
Note: PowerApps is the best solution to implement this functionality, this way you can show/hide fields on click/change of dropdown values.

@Ashish_Kohale I hope this is the last conversation :) for this.
Are you able to hide and show columns on the basis of selection/update of values in New or Edit Form (intent to do a real time evaluation of parent column and then show and hide of child column ). If your answer is "yes" then that is not happening for me and for me that is a show stopper for me.

@Vikram_Samal : Yes I understood yours query totally. All I wanted to say the formula is working but not on real time value changes(which I have explained pretty in my earlier post with screenshots), it takes effect only after saving the value.
Once you apply formula on specific column to which you want to show/hide based on value of another column. And then create New item,select column value based on show and hide of another column and then save the item and open the same item again, the formula working on both display/edit form.
In order to work this in real time we need to customize the form with PowerApps, where we can get more controls to apply such condition.
Its really awesome such tech community where we get to know various people and discuss with them. It gives us opportunity to Share and Learn.

Hi @Vikram_Samal, thank you for your answer.
I understand that Power Apps is the solution to create custom form but I had hope that SharePoint could have a simple feature like this because the formula is available for the edit mode too.
It is complicate to explain to the final users that, yes you have a conditional formula but no it does not work like that.
Create a Power Apps for a simple use case like this one is pretty huge (potentially with authorizations, licences and external sharing).
Anyway, it is noted. That you for your time :)
