Double click on the text, select and delete it.

If you mean to have it blank as default, you need the source code to edit it directly in the code.

I may have misunderstood. Do you mean the variable name or the variable text (right column in your pic)?

For the variable name:

Inserted Code
input string abcdef = "ghjklm"; //

The above will make the variable name blank.

Be sure the code has this in the beginning:

Inserted Code
#property strict

Thanks for replying. But as you can see from this example

input string S1="Trade Settings";

I must enter S1 or something characters except a blank space. I know can use this

input string S1="Trade Settings"; //

To input something after the // , but I just cannot make it show nothing(blank)

To be frank, I never tried to make a variable name blank ... The // is the way I do for rename the variable for better looking in the inputs tab ...

Thanks anyway. But your suggestion of using a dot really does make a difference. Cheers.

It would be interesting to see if someone got a full blank solution. There is one for sure!

Yup. Looks simple but I have tried many ways but just cannot get it. Maybe will try asking the EA developer but guess is trade secret.

I see his EA got use blank String as spacing really makes the Inputs Settings looks neat and clean.

But once again your suggestion of using the dot also do the same thing

Not a trade secret! Just a simple trick (cosmetic). I see no reason for not sharing it.

Enjoy your weekend!

Thank you all and FerruFx in particular for solving my problem.
I was not using the #property strict and it was not working. I was getting the variable name instead of the comment after the //

well it's pretty old question still for people who search it as ppl said u can use //.
but if you absolutely want to have blank not dot or whatever
you can it this way
input "Data Type" myVar="Value"; // ALT + 255
example

input int myVar=0; //Alt +255
it add blank ascii code "not space blank ascii code"
so user in compile version will see empty name
