How to create JSON structure for dropdown within the ribbon with out giving in html as <ul><li>

[Jesu]

Hi, 

I have four questions with this ribbon.

1. Instead of assigning the splitButtonSettings values for the ribbon  in html as is it possible to give it in JSON itself.

2. Assigning dropdown values at run time.

3. Enabling and disabling ribbon menus at run time

4. how to dynamically add tabs at run time.

5. how to add other controls in ribbon without adding jquery can we do this.

Ex:

Instead of giving Targetid and binding in html is it possible to construct it with in json itself

Will this ribbon JSON support Level 4 menus

Hi Jesu, 

 

Thanks for contacting Syncfusion support. 

 

Query 2: Assigning dropdown values at run time. 

 

We are able to assign the dropdown values using “dataSource” property of DropDownList component, please check the below code block. 

 

[TS] 

 

onCreate(e){ 

            var fontFamily = ["Segoe UI", "Arial", "Times New Roman", "Tahoma", "Helvetica"]; 

            var DropDrownObj = $("#Default_fontfamily").ejDropDownList("instance"); 

            DropDrownObj.option("dataSource",fontFamily); 

        } 

 

 

 

Sample. 

 

In our provided sample, we have assign the dropdown values on Create event, please check it in Sample. 

 

To know more details about dataSource property of DropDownList component, please check the below help document. 

https://help.syncfusion.com/api/js/ejdropdownlist#members:datasource 

 

Query 3: Enabling and disabling ribbon menus at run time 

 

We were able to dynamically change the ribbon menu states using enable and disable method of Menu component, please check the below code block. 

 

[TS] 

 

        onEnable(){ 

            var menuObj = $("#ribbonmenu").ejMenu("instance"); 

            menuObj.enable(); 

        } 

        onDisable(){ 

            var menuObj = $("#ribbonmenu").ejMenu("instance"); 

            menuObj.disable(); 

        } 

 

 

To know more details about enable and disable method of Menu component, please check the below api document. 

 

Disable: https://help.syncfusion.com/api/js/ejmenu#methods:disable 

 

Enable: https://help.syncfusion.com/api/js/ejmenu#methods:enable 

 

Query 4: how to dynamically add tabs at run time.  

 

We have provided the addTab method for Ribbon component. You can use this method to dynamically add the tabs at run time. Please check the below code block.  

 

[TS] 

 

onAddTab(){ 

            var tabGroup = [{ 

                text: "New", 

                alignType: ej.Ribbon.AlignType.Rows, 

                content: [{ 

                    groups: [ 

                        { 

                            id: "new", 

                            text: "New", 

                            toolTip: "New", 

                            buttonSettings: { 

                                contentType: ej.ContentType.ImageOnly, 

                                imagePosition: ej.ImagePosition.ImageTop, 

                                prefixIcon: "e-ribbon e-icon e-new" 

                            } 

                        } 

                    ], 

                    defaults: { 

                        type: ej.Ribbon.Type.Button, 

                        width: 60, 

                        height: 70 

                    } 

                }] 

            }]; 

            this.ribbon.widget.addTab("Tab2", tabGroup,3); 

        } 

 

 

To know more details about addTab method, please check the below api document. 

 

https://help.syncfusion.com/api/js/ejribbon#methods:addtab 

Query 1 & 5 : Instead of assigning the splitButtonSettings values for the ribbon  in html as is it possible to give it in JSON itself. Ex: Instead of giving Targetid and binding in html is it possible to construct it with in json itself. 

Currently we don’t have the inbuilt support to render the SplitButtonSettings items without using target API. But we are able to convert the corresponding JSON into ul li element after bind to Split button Targetid. Please find the below conversation code block. 

 

[TS] 

            let ul:any; 

            splitObj = [{ id: 1, text: "Item 1" }, { id: 2, text: "Item 2" }, { id: 3, text: "Item 3" }]; 

            ul = document.createElement("ul"); 

            ul.id = "pasteSplit"; //Split button Target Id 

            document.body.appendChild(ul); 

            debugger; 

            for (let i = 0; i < splitObj.length; i++) { 

                let li = document.createElement("li"); 

                let a = document.createElement("a"); 

                a.innerHTML = splitObj[i].text; 

                li.appendChild(a); 

                ul.appendChild(li); 

            }

Hi Jesu, 

 

Thanks for your update. 

 

Query 1: How to set focus for the tabs on run time? 

 

In our Ribbon component we have provided the “selecteditemindex” property to selected(focus) the tab. You can use this property to focus the tab on run time. 

 

Please check the below API document: 

 

https://help.syncfusion.com/api/js/ejribbon#members:selecteditemindex 

 

Online demo for this requirement in Java Script Platform: https://js.syncfusion.com/demos/web/#!/bootstrap/ribbon/API's 

 

Query 2: I am quite happy with the above answers, but i am little confused with menu enable disable. i want to disable the menu with in the tab->Group->content->group->Id:one. how to get the node element with this order to disable the Id one. 

 

We have checked your query. We suspect that you have rendered the ejMenu component in Ribbon Groups with the help of custom component integration logic.so, the corresponding ul element id as the same for Menu component id. Please check the below code block. 

 

[HTML] 

 

<ul id="ribbonmenu"> 

    <li> 

        <a>FILE</a> 

        <ul> 

            <li><a>New</a></li> 

            <li><a>Open</a></li> 

            <li><a>Save</a></li> 

            <li><a>Save As</a></li> 

            <li><a>Print</a></li> 

        </ul> 

    </li> 

</ul> 

 

[TS] 

 

// 

 

groups: [{ 

          text: "Font", 

          content: [{ 

              groups: [{ 

                                id: "ribbonmenu", 

                                type: ej.Ribbon.type.custom, 

                                contentID: "ribbonmenu" 

                            }] 

             }] 

}] 

 

//To use this method for after ejMenu component creation. 

//Enable 

 

onEnable(){ 

            var menuObj = $("#ribbonmenu").ejMenu("instance"); 

            menuObj.enable(); 

} 

 

//Disable 

 

onDisable(){ 

            var menuObj = $("#ribbonmenu").ejMenu("instance"); 

            menuObj.disable(); 

}
