[CategoryExpanded] set standard to "false"

[sidlercom80]

Good afternoon, everyone. Who can help me with my problem? i have created a lot of settings in my strategy. unfortunately the clarity of the menu has been lost. how is it possible to set the different categories to closed by default when loading the strategy, so that the individual categories have to be opened manually, if necessary. perhaps there is an example?

Hello sidlercom80,

Thank you for your post.

There's not a simple setting to collapse the sections, however, an expandable class would achieve your goal. There's a good example of this on this forum post:

Hello NinjaTrader_Kate , thank you for your help! You don't seem to understand me very well, I think ;-)
I want this to happen when loading the strategy, as default all registers are collapsed in the properties window. this can certainly be done easily by command, i just don't know with which.

Hello sidlercom80,

Thank you for your reply.

I do understand, and unfortunately there's not a supported method to achieve this.

You may be able to use [CategoryDefaultExpanded(false)] to try to display its properties as collapsed.

This is applied at the class level so it applies to all properties that can be collapsed:

[CategoryDefaultExpanded(false)]
public class Test : Indicator
{

However, this is not supported and did not work for strategies in my testing, though it did work for an indicator.

Otherwise, you'd have to try the option for creating collapsible classes.

Please let us know if we may be of further assistance to you.
