Optimajet FormEngine 支援即時 IDE 驗證和自動補全，從而幫助您及早發現問題並改進表單開發。

Optimajet FormEngine is a drag-and-drop React form builder that lets teams create, manage, and render complex web forms without writing frontend code. It allows developers and business users to visually design forms, store them as JSON, and render them at runtime. As a React JS library, it easily integrates into existing applications while giving developers full control over form logic, structure, and data flow, making it well suited for complex data collection.

Optimajet FormEngine enables JSON Schema validation for forms, allowing developers to validate form JSON directly within their IDE, identify structural issues, incorrect data types, and unsupported configurations early in the development process, and enforce a consistent, well-defined structure across all forms. By providing real-time feedback, inline error highlighting, and autocomplete suggestions, it improves accuracy and reduces the need for repeated testing cycles, helping developers work more efficiently while minimizing runtime errors and ensuring more reliable form implementations.

Optimajet FormEngine is licensed based on usage type (internal commercial use, public web/SaaS, or OEM embedding), number of domains for the visual editor, and access to additional ready-made components. Licenses are perpetual and include 6 months or 1 year of updates and support. See our Optimajet FormEngine licensing page for full details.

Annotation support in a Vue.js chart component refers to the capability to overlay additional contextual elements, such as labels, markers, lines, or regions, directly onto a chart to highlight specific data points, thresholds, or events. This feature enables developers to enrich visualizations with meaningful insights without altering the underlying dataset, making it easier to communicate key information such as trends, anomalies, or business rules within the UI.

Several Vue.js chart components support chart annotations, including:

  • Wijmo Vue Chart (FlexChart) (part of Wijmo by MESCIUS) lets you add configurable chart annotations that highlight data points, thresholds, and ranges.
  • DevExtreme Vue Chart (part of DevExtreme Complete by DevExpress) allows you to incorporate annotation layers into charts, supporting labels, shapes, and guides.
  • Highcharts Core by Highsoft facilitates advanced chart annotations with flexible positioning, rich styling, and event handling.
  • Kendo UI Vue Charts (part of Kendo UI Vue Charts by Telerik) enables annotation features within charts that visually emphasize key data elements.

在資料欄位中直接啟用格式化輸入，使內容更清晰、更有結構且更易於操作。

An RTF (Rich Text Format) editor allows users to create and modify formatted text, such as bold, italics, fonts, colors, and embedded elements. This capability is particularly useful in applications where descriptive or user-generated content must retain presentation alongside data, such as CMS platforms, reporting tools, or enterprise data grids. By integrating rich text editing at the component level, it enables more expressive data entry, reduces the need for external editors, and ensures formatting consistency when storing and rendering content across systems.

Several React data editor collections include RTF (rich text format) functionality, including:

  • DevExtreme React Data Editors (part of DevExtreme Complete) facilitates formatted text input and consistent handling of styled content in applications.
  • KendoReact Data Editors (part of by KendoReact Telerik) enables formatted text entry and clear representation of content within application data fields.
  • Sencha Ext JS supports structured text formatting and consistent display of rich content in applications.
  • JQWidgets incorporates formatted input and improves how text content is captured and rendered.

Annotation capabilities in PDF Viewer components allow users to interact with documents through visual and textual markup, supporting review, collaboration, and documentation processes. Tools such as Line, Rectangle, and Free text help highlight structure and add clarity, while Sticky note and Stamp annotations provide contextual feedback and status indicators. By embedding these capabilities directly into a viewer, applications can offer a cohesive experience for editing and reviewing PDFs without requiring external software.

Common annotations include:

  • Ellipse annotations offer a circular or oval shape tool for highlighting regions in a less rigid form than rectangular annotations.
  • Free text annotations let users insert editable text anywhere on the page for inline commentary or corrections.
  • Freehand draw (Ink) annotations enable natural, pen-like input for signatures, sketches, or handwritten notes.
  • Line annotations allow users to draw straight connectors or highlights between points, often used for pointing out relationships or alignment.
  • Rectangle annotations provide a way to frame areas of interest, making it useful for emphasizing sections of a page.
  • Stamp annotations apply predefined or custom labels, such as approval or review statuses, directly onto the document.
  • Sticky note annotations add comment markers that can store detailed feedback without cluttering the document visually.

設計使用帶狀模式的 Vue.js 應用程式來組織命令、輸入和控制項，以加快存取速度。

Ribbon bars are graphical user interface (GUI) patterns that organize commands and features into a series of tabs, each containing grouped controls such as buttons, dropdowns, and galleries. Widely adopted in modern software applications, ribbons present functionality in a structured and visually accessible layout to improve discoverability. This approach reduces reliance on deeply nested menus and toolbars, enabling users to locate relevant tools more quickly based on context.

Several Vue.js user interface suites provide ribbon functionality, including:

  • Wijmo by MESCIUS enables ribbon-style interfaces using components such as TabPanel to organize commands into tabs with grouped controls.
  • jQWidgets provides a ribbon-like structure, which offers tabbed navigation and allows developers to embed toolbars, buttons, and layouts to create grouped command areas.
  • SmartClient by Isomorphic Software supports ribbon-style interfaces, allowing developers to construct tabbed navigation with organized command groups.
