Field dependancy : display a textfield dependant from a custom multi-enum

this.on("render", this.<function_name>, this);

By putting the render, and by copying my code in create-actions.js, i finally did it ! My final code  in the next response :)

({    extendsFrom: 'RecordView',
    initialize: function(options) {
  this._super('initialize', [options]);
  this.on("render", this.displayFunction, this);//launch it whenever your page is rendered
  this.model.on("change:YourMultiSelect",this.displayFunction, this);//display changes when the multi select change
    },
 displayFunctiondisplayDetailsScoring:function(){
  if (_.indexOf(this.model.get('YourMultiSelect'), "others") === -1){
   $('[data-name="YourTextField"]').hide();
  }else{
   $('[data-name="YourTextField"]').show();
  }
},
}) 

({    extendsFrom: 'RecordView',

({    extendsFrom: 'CreateActionsView',

Sorry if it seems out of place , thought to keep the discussion linked since I'm building on this.

Anyone figured out how to style things as closely as possible to sugarcrm default behaviour ( dependent field ) . for .show and hide ?

Tried multiple things such as addClass("hide") instead of .hide and removeClass("hide").

, searched the style guide but couldn't find it. Basically the rows will collapse and the other field will take full width if there's more than 1 on the same row and one of them shows as hidden. This doesn't happen on dependent fields. Recordit: Record screencasts fast & free! with GIF Support!

UPDATE

It seems to be the vis_action_hidden class so my code now looks something like : However can't get that pink coloured fade-in effect.

            if(this.model.get('objectifs_c').contains("12") ) { //programation action commerciale
                $('[data-name="v_liste_actionco"]').removeClass("vis_action_hidden");
            }


            else {
                $('[data-name="v_liste_actionco"]').addClass("vis_action_hidden");
            }

I worked on exactly the same issue in Sugar 9.2. We have a multi-select field in the Meetings module where one of the choices is "Other". A text field had to be displayed when "Other" is one of the selections. First, I set it up as shown by Gaelle Fernandez, using the ".hide" and ".show" methods. This worked to some degree, but not well enough. When the multiselect options were initially entered, the text field would not open when "Other" was selected. Instead, the text field would show a message on mouse-over: "This field is locked because it is involved in a running process" (see image). But, if I saved the meeting and then edited it, the text field would open when "Other" was selected, as expected. When I replaced ".hide" and ".show" with ".removeClass" and ".addClass", as shown by Caim Astraea, everything started to work as expected. Thank you all!

I am new to sugarCRM. Recently I have searched for the same solution and google drop me here. I tried the above solutions but they are working for only dropdown field. Since, sugar logic is not working for multiselect field dependency. Multiselect field dependency keeps values as Objects. SO, by converting it into array and iterating the array we can find whether the multiselect field contains our required value or not.

I know this this is very late but this will be helpful for the future readers like me.

//solutions_c is Multiselect field
//revenue_c is Textfield

initialize: function(options) {
    this.plugins = _.union(this.plugins || [], ['HistoricalSummary']);
    this._super('initialize', [options]);

    //declare onChange
    this.model.on("change:solutions_c", this.SolutionsOnChange, this);
},

SolutionsOnChange: function(){
    var solutionsField = this.model.get('solutions_c').toString();
    var flag = 0; //set flag as 0
    //exploid by (,)
    var solutionsArray = solutionsField.split(",");
    for(var i = 0; i < solutionsArray.length; i++ ){
        if(solutionsArray[i] == "Electronics"){
            flag = 1; //set flag as 1
        }
    }
    if(flag == 1){
        $('[data-name="revenue_c"]').css('visibility', 'visible');
    }
    else{
        $('[data-name="revenue_c"]').css('visibility', 'hidden'); 
    }
},

Thank you,
